Laser Beam Diagnostics

Lasers are ubiquitous in industry today. Carbon Dioxide, Nd:YAG, Excimer and Fiber lasers are used in many industries and for a myriad of applications. Each laser type has its own unique properties that make them more suitable than others. Nevertheless, at the end of the day, it comes down to what does the focused or imaged laser beam profile look like at the work piece?

Laser Beam Analyzer System

The Haas Laser Technologies Laser Beam Analyzer System is a modular design. The patented design contains “no moving components” and provides instantaneous 2-D and 3-D measurements, analysis and monitoring through more than one Rayleigh range of the laser beam and all active optical elements. The system includes software, sensors and attenuation modules for all laser wavelengths and laser powers.

In every laser application, the laser beam profile provides valuable information for the most efficient use of the laser. The system can measure and monitor the following:

 M2, K and BPP values

 Beam Waist size and location

 Spatial profile

 Focus shift

 Divergence

 Circularity

 Rayleigh Length

 Astigmatism

 Centroid

 By monitoring the above values, you have early warning of any problems with the laser and entire beam delivery system. This relates to increased quality, process reliability, and reduced scrap.


The BWA-PROTM  software is designed based on the international standards ISO 11146 and ISO 13694 which relate to lasers and laser related equipment and laser beam spatial metrics. The ISO standards are generic in nature allowing for several different laboratory setups and testing techniques.

The BWA-CAM® is a patented (USPTO 8,237,922; 8,427,633; 8,619.247; 8,711,343; 8,848,177; 8,848,178; 8,848,179; 10,708,537; 10,942,275) instrument that measures the focal beam waist of a laser beam without moving parts.

The BWA-PROTM  software uses full image based second moment and knife edge to determine quick and reliable ISO beam parameters. Calculated results can be viewed in tabular form as well as logged to view changes over time. A sophisticated, yet easy to use, report generator produces a variety of QC and summary reports in PDF formats for publication or printing. The reports include visualization windows, X and Y axis plots, 3D view of laser beam and database reports.

The software is specifically designed to support Windows XP / Vista/Windows 7/ Windows 10 operating systems. It is available as 32 Bit / 64 Bit versions and can control up to four beam profiler cameras on a single computer.
