New Portable Beam Profiler Optimises Nd:YAG, Diode and Fibre Laser Beams up to 150W

Ophir-Spiricon, the global leader in precision laser measurement equipment, has recently announced the BA150 Industrial Laser Beam Analyser. The BA150 is a laser beam profiling system that analyses key laser parameters in order to maintain peak performance of precision material processing lasers. A compact, self-contained unit that fits in almost any glove box type laser system, the BA150 includes a state-of-the-art USB 2.0 silicon CCD camera and advanced beam analysis software. The system monitors all key laser beam parameters for 1064nm pulsed and CWindustrial Nd:YAG, diode, and fibre lasers up to 150W.
The BA150 is an integrated system, so there is no need for beam modifying splitters, attenuators, or other components.

The BA150 Industrial Laser Beam Analyser measures a variety of parameters, including beam profile, average laser power, energy per pulse, pulse rate, and temporal pulse width. All measurements are made independently of the laser power supply and can be output to a PC to be recorded in digital form for storage and analysis. The system can be set to flag deviations from normal beam parameters for process control.

The BA150 is based on the company’s new SP620 USB 2.0 Silicon CCD Camera designed specifically for laser beam measurement applications. The SP620 features the highest dynamic range in the industry, up to 64dB; a programmable, high-speed electronic shutter; and a photodiode synch to capture scattered laser light at even the most challenging nanosecond pulse rates.

“The BA150 is designed for high precision applications where the laser beam profile, temporal pulse shape, laser energy per pulse, and frequency of the laser must work as specified,” stated Ephraim Greenfield, VP Engineering, Laser Measurement Group, Ophir-Spiricon, Inc. “In YAG welding and cutting, for instance, if the laser goes out of spec in any way, it can significantly affect the quality of the work and result in extensive scrap. The BA150 is designed to improve customer yields in a compact, portable unit that measures converging and focused beams, whenever and wherever needed,”
