Slight changes in the beam profile of high-power laser systems can cause severe consequences. The Beam Waist Analyser Monitor (BWA-MON®) by Haas Laser Technologies provides users with continuous real-time data covering the entire laser beam profile. Mistakes are detected as they happen and can be fixed before damage occurs.

The BWA-MON® is the only monitoring system without any moving parts. It uses an identical reflection of the actual beam to determine characteristics like beam waist and size, M-squared or thermal lensing. Working at 50Hz, the system allows for several measurements per second.

Thanks to its modular build, the BWA-MON® can easily be adapted to the needs of any specific application.

In Europe, Haas Laser Technologies products are exclusively sold by Laser Components.
