1 Basic safety instructions
Intended use
The CompactPowerMonitor CPM is exclusively intended for measurements which are carried out in or near-
by the optical path of high power lasers. Please mind and adhere to the specifications and limit values given
in chapter 18 „Technical data“ on page 48. Other forms of usage are improper. The information contained
in this operating manual must be strictly observed to ensure proper use of the device.
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 class 4). That is why the applying safety regu-
lations 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 ANSI Z 136 “Laser Safety Standards” and ANSI Z 136.1 “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.
Necessary safety measures
If people are 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 must be implemented:
• 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.
• Protect yourself from direct laser radiation, scattered radiation, and beams generated from laser radiation
(by using appropriate shielding walls, for example, or by weakening the radiation to a harmless level).
• Use beam guidance or beam absorber elements that do not emit any hazardous substances when they
come in to contact with laser radiation and that can withstand the beam sufficiently.
• Install safety switches and/or emergency safety mechanisms that enable immediate closure of the laser
shutter.
• Ensure that the device is mounted securely to prevent any movement of the device relative to the beam
axis and thus reduce the risk of scattered 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 and modifications
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.

5 Introduction
5.1 System description
The CompactPowerMonitor CPM is a measuring device for the determination of the laser power of laser
beams in the multikilowatt range. The main field of application is the control of laser powers of CO2or solid-
state lasers as well as high power diode lasers available at the work piece. The device is able to measure
both collimated and divergent beams.
5.2 Measuring principle
The CompactPowerMonitor CPM measures the laser power according to a calorimetric principle. The irradi-
ated laser power is absorbed by a water-cooled absorber inside the device. By measuring the cooling water
flow rate and the respective temperature difference between the inflowing and the outflowing water, the
absorbed power is determined.

8 Connect cooling circuit
DANGER
Fire hazard; Damage/Destruction of the device due to overheating
If there is no water cooling or a water flow rate which is insufficient, there is a danger of
overheating, which can damage the device or set it on fire.
X
Operate the device with a connected water cooling only and a sufficient water flow rate (see
chapter 8.5 on page22).
X
Connect the laser control’s safety interlock with the device. The safety interlock is only re-
leased if there is a minimum of cooling.
8.1 Water quality
NOTICE
Damage/Destruction of the device due to different chemical potentials
The parts of the device which get in contact with cooling water consist of copper, brass or
stainless steel. Connecting the unit to a colling curcuit containing aluminum components
may cause corrosion of the aluminum due to the different chemical potentials.
X
Do not connect the device on a cooling circuit in which aluminum components are installed.
• The device can be operated with tap water as well as demineralized water.
• Do not operate the device on a cooling circuit containing additives such as anti-freeze.
• Do not operate the device on a cooling circuit in which aluminum components are installed. Especially when
it comes to the operation with high powers and power densities, it may otherwise lead to corrosion in the
cooling circuit. In the long term, this reduces the efficiency of the cooling circuit.
• Should the cooling fail, the device can withstand the laser radiation for a few seconds. In this case, please
check the device as well as the water connections for damages.
• Large dirt particles or teflon tape may block internal cooling circuits. Therefore, please thoroughly rinse the
system before connecting it.
An operation with strongly deionized water (DI-water, conductivity < 30µS/cm) is only possible with
the respective connection parts – we would be glad to advise you as necessary.
8.2 Water pressure
