Other Equipment

For industrial multi kilowatt applications

  • air- or water-cooled systems
  • Power: water-cooled systems: > 12 kW, air cooled systems: up 4 kW
  • Power densities: plain absorber up to 1,2 kW/cm2, inclined absorber up to 6 kW/cm2
  • can be used directly beneath the processing area

Application

Somtetimes it is required in material processing to absorb the laserradiation bedind the focal point.

Laser sources working with mechanical a shutter need o beam dump.

 

Technical description

A highly absorting coating enables to dissipat laser power even in the multi kilo watt range.

The coating work also for Nd:YAG - laser radiation even with reduced efficency.

for integration into laser system

The BeamControlSystem is designed for the measurement of the most significant beam parameters in the field of industrial produc-tion. Not only the laser power but also the focus spot geometry are determined by the system which is completely dustproof.

Application

This integrated system includes the functio-nality of  three PRIMES products:

  • FocusMonitor
  • CompactPowerMonitor
  • Profibus-Interface


Therefore, it is ideal for the integration into a laser system.

The combination device is completely dust-proof. In the stand-by mode the beam entrance is sealed by a pneumatic shutter. This ensures a steady protection of the measuring devices from pollutions in rough industrial environments. 

Features of BeamControlSystem:

  • Power measurement up to 10 kW
  • Focus analysis from 0.2 mm to  3 mm
  • Power density in the focus up to  10 MW/cm2 (@ 800 nm tos 1100 nm)
  • Wavelength ranges: 800 to1100 nm, or 9 to 11 µm
  • PLC Interface enabling  the communication with laser- or system-control
  • Script-controlled, automatic measurements
  • Observation of limit values for beam parameter
  • Dust-proof housing
  • Electro-pneumatic shutter

Technical description

Using script control, a feature of the PRIMES LaserDiagnosticSoftware, enables a fully automated analysis of the laser power as well as the focus geometry. 

The EVALUATION function enables a comparison of the measured data with prescribed limiting values. Corresponding alarm signals are then passed on to the laser - or system -control. Altogether, it allows a fully automated observation of the beam parameters. 

Controlled beam parameters:

  • Laser power, typ. ± 3 %
  • Focus position in z, app. 10 % zR
  • Focus diameter, app. ± 5 %
  • Rayleigh length, app. ± 5 %
  • Beam parameter product, typ. ± 10 %
  • M2, app. ± 10 %
  • Ellipticity, typ. ± 10 %
  • Astigmatism, typ. ± 10 %
  • Beam pointing z, typ. ± 0,2°
