Abstract
A device that can be used with high repetitions, high power, pulsed laser ams for beam diagnostics is described. The device utilizes a plurality of hole gratings made from wires or beam attenuators which are positioned in the laser beam by a synchronization technique for firing the high power pulsed laser. Each grating is in the high power beam for one pulse and is then out of the beam for (n-1) pulses, when n is the number of gratings used, to allow for cooling before it is used again.
