Paper Abstract

Experimental results on a pulsed e-beam sustained discharge CO laser are reported. The gas was cooled down to a temperature of 5¡ C, the active volume was 1.5 1. Optimizing gas composition, gas pressure, and output mirror reflectivity, pulse energies up to 8 J corresponding to a specffic value of 16 J / lbar could be demonstrated. The spectrum of the laser radiation was analyzed, lines between 2.8 and 3.3 ?m were found. In burst mode operation, up to 100 pulses at pulse frequencies up to 30 Hz have been achieved, resulting in an average laser power of 60 W.
