1 General Description of the FemtoFiber smart System
Ultrafast fiber lasers provide an ideal combination of system parameters: Small form factor at low cost,
but on the other hand reliable and having brilliant laser performance. Various bulky and cost-consuming
solid-state laser concepts are therefore getting more and more replaced by robust and reliable turnkey
fiber lasers.
T
OPTICA´s FemtoFiber smart lasers are the most compact and cost-effective laser sources for Terahertz
generation. Other applications benefiting from the FemtoFiber smart laser solutions are e.g. metrology
systems, light sources for microscopy, ophthalmology or medical surgery/ examination.
The FemtoFiber smart laser systems are based on rare earth doped fibers and saturable absorber mirror (SAM) mode-locking technology. Generally, the fiber technology ensures a very compact design and
highest robustness against vibration or mechanical shocks. The use of mass produced fiber components
with the proof of Telcordia standards provides an unique cost-benefit ratio. The passive SAM device
ensures self-starting and reliable mode-locking.
Key Features for all systems of the FemtoFiber smart family:
•Turnkey
•Compact
• State of the art FemtoFiber technology: robust and reliable all- fiber setup
• Fiber coupled output
• All necessary control electronics inside
• Telcordia proved components
NOTE ! Please refer to the website www.toptica.com for detailed specifications of the FemtoFiber
smart.
For individual laser system specifications, please refer to the Production and Quality Control Data Sheet.
The FemtoFiber smart lasers are plug & play systems for both OEM integrators and single unit customers.
They provide an electrical interface for remote control and only need 12 ± 2 V DC filtered supply input for
all internal electronics. For single system users the supplied Switch Box provides all switches, supply and
status lines to run a FemtoFiber smart as a stand-alone system without integration environment.
Alternatively, FemtoFiber smart laser heads can also be controlled via an USB-interface.
1.1 Ytterbium Fiber Lasers
PicoFYb 1030/1064
The PicoFYb laser systems are fiber-based picosecond oscillators for seeding industrial laser systems, e.g.
for micro-machining. The PicoFYb laser pulses with excellent amplitude and frequency jitter parameters
are amplified to typical multi-Watt levels in the MOPA (master oscillator, power amplifier) laser or regenerative amplifier systems of our customers. Typical amplifiers are slab, rod and disc lasers operating in the
1 µm wavelength regions.
FemtoFYb 1030
The FemtoFYb laser systems are fiber-based sub-picosecond to femtosecond oscillators for seeding
industrial laser systems, e.g. for micro-machining. The FemtoFYb laser pulses with excellent amplitude and
frequency jitter parameters are amplified to typical multi-Watt levels in the MOPA (master oscillator,
power amplifier) laser or regenerative amplifier systems of our customers. Typical amplifiers are slab, rod
and disc lasers operating in the 1 µm wavelength regions.

1.3 FemtoFiber smart Switch Box (Optional)
The FemtoFiber smart Switch Box is a small tool which provides all switches as well as supply and status
lines necessary to run a FemtoFiber smart laser as a stand-alone system without integration environment
and therefore is recommended especially for single-system users.
Figure 1 FemtoFiber smart Switch Box
NOTE ! All FemtoFiber smart lasers are principally designed for OEM integration.
For stand-alone operation of a FemtoFiber smart: In order to achieve full accordance with
general and nation-specific laser safety regulations (IEC 60825, CDRH, etc.), it is necessary
to supply a FemtoFiber smart laser with a Switch Box at all time !
1.3.1 USB-Control
All FemtoFiber smart laser heads are equipped with a serial USB interface for remote control of the laser
and to integrate it into software environments.
In order to establish an USB connection a USB cable (max. 2 meters length) and a suitable computer
with a free USB 2.0 port are needed. For further details of the USB-Control please refer to section 4.3.3.
NOTE ! A FemtoFiber smart laser system operated without Switch Box, but instead with 12 V direct
power supply and USB remote control, is officially not approved by T
applications. This combination would circumvent the general laser safety regulations (no
interlock mechanism, no lockable power key-switch etc.). T

FemtoFiber smart Manual 2. Safety Instructions and Warnings
DANGER ! During installation, maintenance and service, all persons in the room must wear appropriate
laser safety goggles while the laser is in operation. The recommended protection stage is
dependent on the laser system.
Use appropriate eyewear and other protective means in order to keep radiation exposure
below the maximum permissible levels allowed by applicable regulations (examples: OSHA
limits in the US, BGV B2, BGI5092, TROS Laserstrahlung in Germany).
To determine the protection level of the laser safety goggles required for e.g. FemtoFErb 780
laser system, please refer to the following example: FemtoFErb 780 with collimated beam,
beam diameter 1.6 mm, wavelength = 780 nm, repetition rate 100 MHz, laser power up to 6070 mW generates a peak power density of H
BGI5092 this leads to a required protection level of 780 D LB 4 + M LB 1 for your eyewear.
DANGER ! Laser safety goggles selected for adjustment purposes do not protect against an intention-
ally focused direct beam which will increase the optical power densities by a few orders of
magnitude.
DANGER ! Regular functional checks and performance inspections at the supplier are recommended
for all laser safety goggles.
DANGER ! Do not position the equipment so that it is difficult to operate the disconnecting device.
DANGER ! Use of controls or adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure.
~ 0.3 mJ/m² (approximately). From Table 3 in
M
DANGER ! If the equipment is used in a manner not specified by the manufacturer, the protection pro-
vided by the equipment may be impaired.
DANGER ! The FemtoFiber smart uses very powerful lasers (up to class 3B). Therefore, it is imperative to
take great care and observe the statutory warning labels on the unit.
DANGER ! Do not open the device at any time, FemtoFiber smart is a hands-off laser system. Reflections
of the laser beam may cause serious injury to your eyes. Internal tuning as well as the replacing of components may only be carried out by T
OPTICA. Under certain circumstances there
may be dangerous voltages, even if the device is disconnected from the mains supply.
DANGER ! Do not look into the beam from the Laser Output (depending on the version: free beam, FC/
APC connector(s) on front panel or FC/APC connector at the fiber pigtail) as the output can
exceed the limits for class 1 specified by US laws 21 CFR 1040.10 and 2 CFR 1040.11 and the
Laser Safety Standard EN 60825-1:2014. Take precautions to eliminate exposure to a direct or
reflected beam.
DANGER ! FemtoFiber smart may not be operated in surroundings of flammable gases or fumes.
CAUTION ! Special precautions are necessary if FemtoFiber smart is to be operated in surroundings of
high electro-magnetic radiation such as close to a plasma discharge. Please refer to T
OPTICA
for technical support.
CAUTION ! Since the FemtoFiber smart has power levels which may already destroy optical fibers, please
pay special attention to a clean fiber facet at the output fiber connector. We also recommend to always switch-off the laser emission before the fiber connector is opened/closed!
CAUTION ! FemtoFErb 1560 standard version: While starting the laser it may occur that higher level pulses
are sent out by the laser. This transient phenomenon is due to the fact that the amplifier of
the system starts simultaneously with the oscillator. We therefore recommend blocking the
output beam at the moment when the laser is switched on, or adding the THz option.

FemtoFiber smart Manual 4. Operation
4.3 FemtoFiber smart System Quickstart
CAUTION ! Since the FemtoFiber smart has power levels which may already destroy optical fibers,
please pay special attention to a clean fiber facet at the output fiber connector. We also
recommend to always switch-off the laser emission before the fiber connector is opened/
closed!
CAUTION ! While starting the laser it may occur that higher level pulses are sent out by the laser. This
transient phenomenon is due to the fact that the amplifier of the system starts simultaneously with the oscillator. We therefore recommend blocking the output beam at the
moment when the laser is switched on, or adding the THz option.
NOTE ! The FemtoFiber smart is specified to be ready for operation within 15 seconds after switch-
on, provided that the laser emission start signal is given right after the boot-up sequence,
which takes approx. 3 seconds. The end of the boot-up sequence is indicated at the laser
head when the Power ON LED (1, blue) and the Temperature OK LED (2, green) light up
(all other LEDs are off).
If laser emission is activated before reaching this state, an error may occur, indicated by
the Clip Error LED (3, yellow) or Module Error LED (4, red).
4.3.1 OEM Integrated Environment
1. Connect the FemtoFiber smart laser to the application via the I/O connector (9). For pin assign-
ment please see section 6.2.
2. Connect the FemtoFiber smart laser Output FC/APC connector (7) to the application.
3. When the FemtoFiber smart laser supply voltage (pin 1 of the I/O connector (9)) is applied and the
TTL input (pin 7 of the I/O connector (9)) is in state high, the laser emission is ON.

Baudrate and Settings are preset and fixed for FemtoFiber smart operation. Click OK to save the
settings and to close the window.
NOTE ! If there is no USB serial port found in the TOPAS FemtoFiber smart list of available lasers -
although the laser is properly connected, switched on and ready to work, it probably
helps to try one of the following solutions:
1) Try to run TOPAS FemtoFiber smart in "XP compatibility mode" (right click on the TOPAS
icon > properties > compatibility). This feature is forcing Windows to emulate XP conditions
and may solve port access issues.
2) Try a "right-mouse-click" on the TOPAS icon and select "run as administrator". Independently from the individual user rights of the computer, TOPAS FemtoFiber smart is run under
administrator rights, without needing to have a password.
3) The USB cable is probably too long or the outputs at the USB port of the computer are
very low. The first problem may appear when the USB-cable is longer than 2 meters. The
second one often appears when a laptop or a tablet computer is used. In both cases, the
signal gets too weak at receiver's side and the communication may be disrupted. In our
experience, establishing the first connection is usually still possible, but in some cases
exchanged commands get lost and either GUI or laser are not operating properly. Do not
use a USB cable longer than the factory supplied one. Alternatively you can try to use a
powered USB hub with an external power supply.
5. Select Menu > Connect to establish a connection to the device.

6.8 Precautions for Non-Condensing Operation Conditions
For FemtoFiber smart lasers, the typical temperature inside the housing is approximately 4 °C above the
ambient temperature. This means, however, that especially in warm and humid surroundings, there
could be condensation at relatively cold parts of the FemtoFiber smart – this is a condition that has to be
prevented. Please refer to the dew point table below to see if the environmental conditions are appropriate for the operation of the FemtoFiber smart.
A safe operating condition for the FemtoFiber smart is reached when the dew point is below the typical temperature inside the housing. For safety reasons, there should be a small margin of 2 °C. Please
check with the dew point table whether at your ambient conditions there may be a risk of condensation.
