Abstract (en)
[origin: WO2015185152A1] The invention relates to a device comprising a drive laser assembly having a beam source for generating a laser beam (7) and having an amplifying assembly for amplifying the laser beam (7), and comprising a unit (15) for monitoring the laser beam (7), having a transmitting optical element (12), in particular a plane-parallel plate, the normal direction (12a), in relation to the beam axis (7a) of the laser beam (7), of which element is arranged at a tilt angle (ß), and a position-sensing detector (16) for detecting laser radiation (13a, 13b) reflecting back on the optical element (12). The optical element (12) has a first side (14a) and a second side (14b) which are arranged at a wedge angle to one another, and through which the laser beam (7) passes, said first side (14a) reflecting a first sub-beam (13a) and the second side (14b) reflecting a second sub-beam (13b) of the incident laser beam (7). The unit (15) has an optical filter (20) that prevents one of the two reflected sub-beams (13b) from reaching the detector (16). The invention also relates to a corresponding method for monitoring a laser beam (7).
