The BWA-MON by Haas Laser Technologies uses a decoupled beam for continuous real-time monitoring. Thus, the beam waist of high-power lasers can be measured during operation and the laser can be characterized in real time (M², spot size, focus position,...). The measuring principle supports several complete measurements per second, so that the formation of a thermal lens can be gecognised immediately – naturally, the same applies to other time-dependent effects such as mode hopping. In addition to this, real-time monitoring also simplifies the laser alignment procedure.

The system design allows ISO 11146 and ISO 13694 compliant measurement of the laser parametres without moving parts, which guarantees a high reproducibility of the measurement process. Due to its modular design, the BWA-MON can be adapted to the specific requirements of any application.
