Laser Beam Diagnostics

Lasers are ubiquitous in industry today. Carbon Dioxide, Nd:YAG, Excimer and Fiber lasers are used in many industries and 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, Cameras, Telescopes and Attenuation modules 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 beams spatial profile, circularity, centroid, astigmatism and M2 values, 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.

The Haas Laser Beam Analyzer System design contains no “moving components” and provides instantainuous measurements and analysis of the laser beam and all active optical elements.

The modular components are as follows:

BWA-CAM

The BWA-CAM Laser Beam Analyzer system and software enables "real-time" laser beam measurement, analysis and monitoring of low to very high power CW and pulsed lasers. The system design is based on the international standards ISO 11146 and ISO 13694 which relate to lasers and laser related equipment and laser beam spatial metrics. In every laser application, the laser beam profile provides valuable information for the most efficient use of the laser. By monitoring the laser beams spatial profile, circularity, centroid, astigmatism and M-squared values, 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.

The BWA-CAM is a patent pending (USPTO 12/756,476) 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.
