Cube L1
1 Basic safety instructions
Intended use
The Cube L1 is used to measure power in the beam path of lasers. Please observe and
adhere to the specifications and limit values given in chapter19, „Technical data“, on
page44. Other forms of usage are improper. The information contained in this operating manual must be strictly observed to ensure proper use of the device.
Measurements with the CubeL1 should be performed exclusively with a static (unmoving) laser beam. While crossing over the absorber structure, moving beams can
produce faulty measurements during the exposure time, thus also producing the associated faulty power measurements.
Using the device for unspecified use is strictly prohibited by the manufacturer. By usage
other than intended the device can be damaged or destroyed. This poses an increased
health hazard up to fatal injuries. When operating the device, it must be ensured that
there are no potential hazards to human health.
The device itself does not emit any laser radiation. During the measurement, however, the laser beam is guided onto the device which causes reflected radiation (laser
class4). That is why the applying safety regulations are to be observed and necessary
protective measures need to be taken.
In measuring mode, the laser control’s safety interlock must be connected with the
device.
Observing applicable safety regulations
Please observe valid national and international safety regulations as stipulated in ISO/
CEN/TR standards as well as in the IEC-60825-1 regulation, in ANSIZ136 “Laser
Safety Standards” and ANSIZ136.1 “Safe Use of Lasers”, published by the American
National Standards Institute, and additional publications, such as the “Laser Safety
Basics”, the “LIA Laser Safety Guide”, the “Guide for the Selection of Laser Eye Protection” and the “Laser Safety Bulletin”, published by the Laser Institute of America, as well
as the “Guide of Control of Laser Hazards” by ACGIH.
Taking necessary safety measures
If there are people present within the danger zone of visible or invisible laser radiation,
for example near laser systems that are only partly covered, open beam guidance systems or laser processing areas, the following safety measures need to be taken:
8
Revision 01/2019 EN
35,0(6
Cube L1
• Connect the laser control’s safety interlock to the device. Check that the safety
interlock will switch off the laser properly in case of error.
• Please wear safety goggles adapted to the power, power density, laser wave
length and operating mode of the laser beam source in use.
• Depending on the laser source, it may be necessary to wear suitable protective
clothing or protective gloves.
• Please protect yourself from direct laser radiation, scattered radiation as well as
from beams generated from laser radiation (e.g. by using appropriate shielding
walls or by weakening the radiation to a harmless level).
• Please use beam guidance- or beam absorber elements which do not emit any
hazardous particles as soon as they get in contact with laser radiation and which
resist the beam sufficiently.
• Please install safety switches and/or emergency safety mechanisms which enable
an immediate closure of the laser shutter.
• Please ensure a stable mounting of the device in order to prevent a relative motion
of the device to the beam axis of the laser and thus to reduce the risk of stray
radiation. This in the only way to ensure optimum performance during the measurement.
Employing qualified personnel
The device may only be operated by qualified personnel. The qualified personnel must
have been instructed in the installation and operation of the device and must have a
basic understanding of working with high-power lasers, beam guiding systems and
focusing units.
Conversions, modifications and repairs
The device must not be modified, neither constructionally nor safety-related, without
our explicit permission. The device must not be opened e.g. to carry out unauthorized
repairs. Modifications of any kind will result in the exclusion of our liability for resulting
damages.
Liability disclaimer
The manufacturer and the distributor of the measuring devices do not claim liability
for damages or injuries of any kind resulting from an improper use or handling of the
devices or the associated software. Neither the manufacturer nor the distributor can be
held liable by the buyer or the user for damages to people, material or financial losses
due to a direct or indirect use of the measuring devices.

Fig. 9.1: Connections
9.1 Safety interlock
At temperatures over 200°C, the safety interlock is triggered in order to protect the
absorber from overheating. If the absorber is hotter than 200°C, Pin3 and Pin4 will
connect.
Due to the concentration of heat in the area of the incident laser beam, the temperature
of the absorber may exceed 100°C for a short time. This brief temperature peak of the
absorber poses no danger to the absorber and the current measurement can be completed. However, if the temperature of the absorber exceeds 100°C after the measurement has been completed, the safety interlock is triggered to protect the absorber.
Once the absorber cools off, Pin1 and Pin4 of the safety interlock are connected. A
suitable 2m long connection cable is included.

12.2.2 Minimum energy per single measurement
The energy used for the measurement must achieve a sufficiently high temperature in
the absorber to be recorded with high precision. Typically, an energy of approx. 500J is
recommended, as long as the measuring duration is <2s.
Example: With a laser power of 1kW and an irradiation time of 500ms, 500 J are
absorbed.
E = P·t = 1000W · 0.5s = 500J

12.3 Series measurement
Always start a measurement series with the smallest power and increase it gradually.
Small amounts of energy should be measured with absorber temperatures that are
close to the ambient temperature.
In general:
The minimum amount of irradiated energy should amount to approximately twenty times
the difference of the absorber temperature minus room temperature, so at least 200J.
In case of subsequent measurements, the residual capacity of the absorber for another
laser pulse has to be considered. Fig. 12.4 on page26 shows information for selecting the energy permissible for a series measurement in conjunction with the absorber

12.4 Measurement with pulsed lasers
When it comes to pulsed laser radiation a correct exposure time measurement up to a
pulse frequency of 10kHz and a duty cycle of 50% is possible. In case of on/off times
shorter than 50μs a correct exposure time measurement is not possible.
With pulsed lasers, the device recognizes the number of pulses n and the number of
pulse pauses n-1. Since the last pulse pause t
and this would lead to an increased display of the average power with a low number of
pulses, the average power is corrected on the basis of the corrected burst duration (see
