Abstract

Apparatus and method for measuring the radiation power of a laser. Two partially transmitting mirrors are arranged in the main laser beam which, with respect to their orientation in space, are turned by 90.degree. with respect to one another and by which a portion of the radiation is coupled out, and the partial beam is directed to an electro optic transducer. The measuring arrangement is therefore independent of the polarization condition of the main laser beam.
