LASER SAFETY
VISIBLE AND/OR INVISIBLE LASER RADIATION
CAUTION: The Jewel Laser is a Class 4 OEM laser. Its output beam is, by definition, a safety and fire hazard. Precautions must be taken to prevent accidental exposure to both direct and reflected beams.
Precautions for Safe Operation of Class 4 OEM Lasers:
DO NOT remove the protective covers from the Laser Head. No user serviceable
Jewel Manual v1.1 | Quantum Composers Page 5
components are inside. Exposure to laser radiation when covers removed.
Avoid looking directly at the laser output beam.
Do not wear reflective jewelry while using the laser, as it might cause inadvertent
hazardous reflections.
Use protective eyewear at all times. Consult the ANSI, ACGIH, or OSHA standards listed
at the end of this section for guidance on goggles and safety matters.
Operate the laser at the lowest possible beam intensity, given the requirements of the
intended application.
Increase the beam diameter wherever possible to reduce beam intensity and thus reduce
the hazard.
Avoid blocking the laser beam with any part of the body.
Use an IR detector or energy detector to verify that the laser beam is off, before working in
front of the laser.
Establish a controlled access area for laser operation. Limit access to those trained in the
principles of laser safety.
Maintain a high ambient light level in the laser operation area so the eye pupil remains
constricted, thus reducing the possibility of hazardous exposure.
Post prominent warning signs near the laser operation area.
Provide enclosures for the beam path whenever possible.
Set up an energy absorber to capture the laser beam, preventing unnecessary reflections
or scattering.
Page 6
CAUTION: Use of controls, adjustments or performance of procedures other than those specified in this Operation Manual may result in hazardous radiation exposure.
Follow the instructions within this manual carefully to ensure the safe operation of your
laser. At all times during laser operation, maintenance, or servicing, avoid unnecessary exposure to laser or collateral radiation that exceeds the accessible emission limits listed in "Performance Standards for Laser Products," United States Code of Federal Regulations, 21 CFR 1040.10(d). This information is also available in EN60825-1:1994, Section 8.2, titled “Measurements of Laser Radiation for Determining Classification.”
Preventative Maintenance for Safety: Preventative maintenance is required to ensure the
laser remains in compliance with Center for Devices and Radiological Health (CDRH) Regulations and European Norm (EN) requirements. This laser product complies with Title 21 of the United States Code of Federal Regulations, Chapter 1, Subchapter J, Parts
1040.10, as applicable, and with EN60825-1:1994, Part 1 for a Class 4 laser, as applicable. To maintain compliance, verify the operation of all features listed below, either annually or whenever the product has been subjected to adverse environmental conditions, which may have affected these features and functions.
o Verify that removing the remote interlock connector prevents laser operation. This
connector is located on the end cap of the laser.
o Verify that the laser will operate only with the key switch in the ON position and the
key can only be removed when the switch is in the OFF position.
o Verify that a time delay exists between turning on the Key Switch and the start of
laser firing. The time delay must be long enough to allow action to be taken to avoid exposure to laser radiation.
ELECTRICAL SAFETY
CAUTION: Both the Laser Optics Assembly and Laser Power Supply contain electrical circuits operating at lethal voltage and current levels. Always unplug the system Mains connection and wait at least one (1) minute to allow capacitors to discharge before servicing any part of the laser system.
Consult with the Quantum Composers if repair of the laser electronics is required. Only those trained in high voltage, high current electronics, and who understand the laser circuitry, should be allowed to service and repair the laser electronics. If any such action is required, it is recommended that you contact the Quantum Composers for details.

JEWEL LASER DESCRIPTION
The Jewel is a conductively-cooled 1064/532/355/266nm diode pump laser with output energy pulses up to 15mJ and rep rates up to 20Hz. It is a self-contained laser head, including the diode and Q-switch drivers.
LASER FEATURES
The laser features (Figure 10 and Figure 11) are indicated below.
Figure 10 Jewel Connection Panel
Jewel Manual v1.1 | Quantum Composers Page 11
Page 12
Figure 11 - Laser Features
1. The laser resonator is a highly efficient diode pumped laser (20Hz less than 5W) with a
fundamental output wavelength of 1064nm. The monolithic structure is machined from a single block of stress-relieved aircraft grade aluminum. Resonator mirrors are hard­mounted to the machined resonator bench resulting in an extremely stiff, rugged resonator which is much less sensitive to misalignment then other laser resonators.
2. Systems w/ output harmonics, 532/355/266nm, have an attached nonlinear optics module
(NLO). The 1064nm output of the laser enters the integral nonlinear module. Harmonic generation is performed using non-linear crystal(s). The crystal temperature is tightly regulated by mounting the crystals inside a temperature controlled oven assembly. The output is collinear, with all wavelengths exiting the same aperture.
3. An optional dichroic module can be attached to “scrape” residual wavelengths from the
output beams allowing single wavelength output.

UNPACKING LASER
The laser has been carefully packaged for shipment. If the container arrives damaged in any way, please contact the shipper's agent to be present for the unpacking. Inspect each unit as it is unpacked, looking for dents, scratches, or other damage. If damage is evident, immediately file a claim against the carrier and notify the manufacturer.
It is recommended that the shipping container be kept, for possible shipping, should the unit require repair or maintenance services. If a damage claim has been filed, the container will be needed, to prove shipping damage.
The laser is a turnkey system, designed so that a field service engineer is not required to get the system up and operating properly. The system has undergone extensive testing to verify its conformance to the specifications, prior to delivery.
Before operating the laser, however, it is important to fully understand its main features and controls.
CAUTION: Do not power up the system before thoroughly reading the system description. Use of the controls or adjustments, or performance of procedures other than those specified in this user’s manual my result in hazardous radiation exposure, laser system damage or result in voiding the warranty. Please do not connect the main power until you verify the power switch is in the OFF position.
SYSTEM INVENTORY
The Jewel Laser consists of the following items. Verify that all listed items are present in the shipping container. If there are any shortages or discrepancies, contact Quantum Composers immediately.

SYSTEM SETUP
CAUTION: When utilizing the Remote Interlock capability, use an isolated contact closure such as a relay to avoid generating undesirable ground loops.
CAUTION: Ensure that the system is connected to the proper Mains voltage. The voltage rating is marked on the Laser Power Supply. Operating the system at the incorrect voltage may result in damage to the unit.
CAUTION: Ensure that the Mains power outlet, that the Laser Power Supply connects to, is properly grounded. Poor ground quality could result in exposure
to electrical shock.
Set up laser beam line, with appropriate optics and/or beam dump(s). Set up remote interlock, as needed. Mount Jewel laser to an appropriate, heat sinking surface.
o Apply thermal material between the unit’s bottom, mid-section and the mounting
surface of the heat sink.
DO NOT apply thermal material to mounting feet or alignment pins. Note: The Jewel will operate without a heat sink, but its duty cycle will be
greatly reduced.
o The heat sink must dissipate 4 watts, at a maximum of 35o C, on the bottom surface
of the laser head (See Interface Drawings).
Attach a USB cable from the port of the computer to the port on the Laser Endcap. Attach Power Supply DC cord to the Jewel laser head. Attach Power Supply AC cord to a proper Mains outlet.
COMMUNICATION - USB
The Jewel laser provides a standard USB connection for remote communications. When the Jewel is connected to a remote computer via the USB connection, the computer will recognize the unit as a “QC-LASER”. Drivers will need to be installed for the remote computer to interface to the Jewel laser. Drivers are included on the provided CD. Once the drivers have been installed, the Jewel laser will show up in the Device Manager as a USB to Serial Port Adapter. The Jewel laser can then be communicated with by either the included Jewel Laser application, or by using any generic communication terminal program.

Figure 12 Jewel Software Application Main Window
Page 16 Jewel Manual v1.1 | Quantum Composers
Page 17
LASER OPERATION CONTROL
The user is responsible for ensuring a suitable beam path and appropriate beam dumps are provided, before firing the laser.
1. Pulse Mode – Options are continuous, single shot or burst.
a. Continuous mode – The laser will fire continuously from the time the Fire button is
pressed until the Stop button is pressed. The pulses per second are controlled with the Rep Rate parameter, under System Settings.
b. Single Shot – The laser will output 1 single laser pulse when the Fire button is
pressed.
c. Burst mode - The laser will output the number of laser pulses specified by the Burst
Count parameter, under System Settings. The laser will stop firing at the end of the burst.
2. Diode Current – Current, in Amps, per pulse sent to the laser diode. See the system ATP document for the optimal value.
a. System alignment should typically be done at diode current levels 10 to 20 Amps
below the optimum setting.
3. Diode Pulse Width – In µsec it is the width of the diode current pulse. See the system ATP document for the optimal value.
4. Diode Trigger- The diode can be internally or externally triggered. Default is internal trigger.
5. Qswitch Enable – This box must be checked for normal operation. When not selected, the qswitch will not function preventing output from the laser head.
6. Qswitch Delay – In µsec it is the delay from the start of the diode pulse. See the system ATP document for the optimal value.
7. Qswitch Trigger – The Qswitch can be internally or externally triggered. Default is internal trigger.
8. Wait Count – This setting is in pulses and represents the number of diode pulses before the qswitch is triggered. For example, a setting of 3 would pulse the diode 3 times the qswitch would function on the 4th diode pulse. This parameter is applied to all Pulse Modes.
9. Divide By N – This parameter will set the qswitch to function on every XX diode pulse. For example, a divide by value of 2 will trigger the qswitch on every 2nd, 4th, 6th… diode pulse.
10. Fire button – Selecting the fire button will start laser output. NOTE: the laser must be enabled before the Fire button becomes active.
Jewel Manual v1.1 | Quantum Composers Page 17
Page 18
6. Laser Operation
The laser has undergone extensive testing to verify its conformance to the specifications prior to delivery.
Once the laser has been set up as outlined in the previous chapter, it is ready to operate. Turn the Key Switch ON. After approximately 10 seconds the laser is initialized and ready for operator control. See summary Data Sheets included with our laser for factory preset operating parameters.
CAUTION: Below is a list of guidelines, which apply to all Quantum Composers’ laser systems. These guidelines should be followed whenever possible, to avoid laser damage.
Operate the laser in a dust-free environment, and keep the Laser Optics covered when not
in use. This protects the output aperture against dust and particulate.
The Laser Optics Assembly is sealed with careful attention to use of low outgassing
materials. Silicone and similar sealing, bonding or insulating materials should not be used in close proximity to the Laser Optics because these substances will outgas, and could contaminate the output window, causing laser damage.
Avoid back reflections. Back reflections of even a small percentage of the output energy
can promote damage to optical components in the Laser Head. For example, an uncoated convex lens or a glass disk calorimeter will reflect about 4% of the incident energy. While the reflection may seem harmless, it can perturb the resonator operation to the extent that the near field beam intensity profile is degraded, and may promote optical damage. It may also affect the resonator hold-off, which can cause prelasing and catastrophic optical damage. In some cases, even anti-reflection coated glass optics can reflect enough energy to promote damage to laser optics. It is best to use only quality optics coated for the operating wavelength.
CAUTION: To avoid laser damage, minimize back reflections of the output beam. When reflections are unavoidable, direct them away from the optical axis of the system by canting the optics off-axis. Failure to do so can cause laser damage and
void the warranty.
MANUAL SHUTTER OPERATION
The Jewel Laser utilizes a manual shutter, located at the output of the laser head (see Figure 13). The shutter blocks laser output when in the CLOSED position. An internal switch prevents the laser from firing. The switch is satisfied only when the lever is fully in the OPEN position.

7. DEVICE COMMANDS
Field
Description
Prefix
Single semicolon character ";", must precede all commands. All devices will reset their command input buffer when the prefix is received.
Address
2 ASCII characters. Each device has a unique address which is programmed into its firmware. See the table below for a list of addresses.
Delimiter
Single colon character “:”, must follow device address.
Command String
Commands are specific to each device -- see the following sections for the commands that each device supports.
Parameters
(optional field) Some commands may not require a parameter. For Query commands immediately follow the command string with the question mark character ”?”. For non-query commands immediately follow the command string with a single space character ” “ followed by the parameter. Multiple commands are separated by commas.
Terminator
ASCII carriage return character (ODh). The receiving device does not process any commands until the terminator is received.
Device Command Format
All commands use ASCII characters and are composed of the following fields:
<Prefix><Address>< Delimiter ><Command String>[Parameters]<Terminator>
Device Addresses
COMMAND TYPES
There are two types of commands -- those that set a value or initiate an action (control commands), and those that request information (query commands). Each device must respond in the proper manner to each type of command.
Control Command s
A device must always parse a control command and return a response immediately.
If the command is a recognized command and the parameter is valid, then the device
returns an "OK<CR>".
If the command is not recognized, then the device responds with a "?1<CR>". If the command is recognized, but the parameter value is missing or invalid, then the device
responds with a "?4” or “?5”.
Jewel Manual v1.1 | Quantum Composers Page 21
Page 22
If a control command is received while the device is in the midst of executing a previous
command, and the commands are mutually exclusive (cannot be executed in parallel), then the previous command is aborted and the new one executed. It is up to the host controller (the PC) to poll the device and make sure the previous command has finished, if that is needed.
Query Commands
Query commands return a value to the PC as soon as the command is parsed and executed. The value returned will depend on the command. The response is always terminated with a “<CR><LF>”. If a query command is not recognized by the device, then a "?1" is returned.
Error Codes
?1 Command not recognized. ?2 Missing command keyword. If command requires keyword. ?3 Invalid command keyword. If command requires keyword. ?4 Missing parameter. ?5 Invalid parameter. ?6 Query only, command needs a question mark. ?7 Invalid query, command does not have a query function. ?8 Command unavailable in current system state. ?9 Module timeout error

9. Trouble-Shooting
The JEWEL LASER control electronics are designed to control the laser and warn the user of problems that may occur. The microprocessor-based system monitors the laser system and automatically shuts down if a fault occurs. Software limits have been factory selected to protect the laser system against electrical and optical damage.
NO LASER OUTPUT
1. Check Fault and Interlock Conditions: Query status information using commands listed in the command set. Refer to status to determine if a fault or interlock conditions exists.
2. Check Cables: With the main power OFF and unplugged, check all electrical connections between the Laser Optics Assembly and the Laser Power Supply. Make sure all connections are secured. If any of the cables are not installed properly, the system will not function.
3. Check Shutter Position: The shutter is manually controlled and is located on the side of the laser head. The laser will fire only when the shutter arm is in the open position.
4. Check Energy Setting: Refer to the data parameters supplied in the Data Summary Sheet and make sure the parameters are not set below the lasing threshold. Correct if necessary.
5. Check Q-Switch Settings: Verify that the Q-Switch is enabled.
6. Check Diode and Qswitch triggers. Ensure they are correct for internal triggering or external triggering.
ENERGY IS LOW
1. Resonator Misaligned: If beam quality has degraded, it may suggest that the resonator needs realignment. Contact Quantum Composers for more details.
2. Incorrect Qswitch delay – Qswitch delay typically matches the Diode Pulse Width. Correct value if necessary.
Contact the Quantum Composers for any repair actions necessary beyond those described in this manual. Attempts to adjust, repair or replace any portion of the laser system may cause additional problems and void the warranty.
