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?
By monitoring the laser beam profile you have early warning of any problems with the laser and entire beam delivery optical system. This relates to increased quality, process reliability, and reduced scrap.
Laser Beam Analyzer System
The Haas Laser Technologies Laser Beam Analyzer System is a modular design. The system includes software, sensors, attenuation modules and filters which enable “real-time” laser beam measurement, analysis and monitoring of high power CW and pulsed lasers.
In every laser application, the laser beam profile provides valuable information for the most efficient use of the laser. By monitoring the laser beam's spatial profile, beam waist position, Rayleigh length, circularity, centroid, astigmatism and M2 values, you have early warning of any problems with the laser and beam delivery system. This type of monitoring leads to increased quality, process reliability and reduced scrap.
The Haas Laser Beam Analyzer System design contains no “moving components” and provides instantaneous measurements and analysis of the laser beam and all active optical elements.
The BA-CAM and BWA-CAM 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) instrument that measures the focal beam waist of a laser beam without moving parts. Prior to the advent of the BWA-CAM, all other beam waist analyzer devices have some sort of moving or spinning components which make real time measurement of a laser's M-squared impractical for on-line or real time applications.
A sophisticated, yet easy to use, report generator produces a variety of reports in PDF, Excel, HTML or several other formats for publication or printing. Single page summary reports as well as multi-page reports including all logged data and charts can be produced.
The BA-CAM and BWA-CAM software program uses full image based second moment techniques, knife edge and equation fitting (Gaussian, Super Gaussian, and Super Donut) techniques as well to determine quick and reliable standard beam parameters. Calculated results can be viewed in tabular form as well as logged to view changes over time. Visualization windows include 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.
