Abstract

The design of an automatic system for laser beam alignment and diagnosis is presented. Our conceptual approach to the development of the system is based on the utilization of a multifunctional electro-optic sensor. The system can determine both the energetic-spatial parameters and the spectral content of the source of radiated energy. According to the obtained information, the system is able to control the spatial parameters of the laser beam and to automatically align the optic devices of the laser system. Algorithms are developed which improve the measurement and control accuracy, take into account the influence of the destabilization factors as well as allow to determine the spectral content of the light source on the basis of a quandrant photodiode. Finally, experimental results are presented which confirm the given methods.
