ABSTRACT:
A type of "light barrier" is used to monitor the functionality of the transparent protective element (5) of a transparent laser optical system: additional light (15) is coupled into a lateral surface of the protective element (5) at an angle which deviates from the incidence direction of the laser beam (1, 2). Said light traverses the material of the protective element (5) and then exits again via the lateral surface, where it is detected by a light detector (16). Cracks and fractures of the protective element (5) can be detected by a change in the light received in the light detector (16). If appropriate, this measurement is supplemented by the measurement of the temperature difference between inflowing and outflowing cooling water, as well as by radiation temperature sensors (14) which monitor the local temperature distribution in the protective element (5).
