Paper Abstract

Experimental results obtained from a 500 Hz, 750 W average output power XeCl laser are presented. The dynamical behavior of the pulse energy and optical investigations of the discharge volume pointed out the limits of the present design. There are strong indications that acoustic perturbations currently prevent the efficient operation of the module at repetition rates higher than 500 Hz. To pass the 1 kW level, further improvements must be made. Increasing the discharge efficiency from 1.1% to date will reduce the creation of shock waves. An aerodynamically designed flow loop will help to shift the ratio of fan power to excitation power (currently 40 kW and 66 kW, respectively) to more reasonable values. The additional use of pulse compression techniques will simplify the choice of adequate high-voltage switching elements.
