Abstract

The first experimental results on a repetitively pulsed e-beam sustained discharge CO-laser operating at room temperature are presented. The active laser volume was 3.41. A laser gas mixture of CO:N₂:He equals 1:6:7 has been used in a pressure range between 300 mbar and 600 mbar. The pumping current pulse duration was 7 microsecond(s) . The laser resonator consisted of a concave rear copper mirror (R equals 9 m) and a plane ZnSe output mirror of 97% reflectivity. The laser operated in a burst mode, the burst length varying between 0.1 s and 10 s at pulse repetition rates between 1 Hz and 50 Hz. The maximum laser energy of a single pulse was 24 J, at 45 Hz pulse repetition rate a medium output power of about 1 kW has been obtained. Further improvements of the laser and its application potential are discussed.
