BeamControlSystem

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°
