MULTIJOULE PULSES FROM CO2LASERS

摘要: A high voltage transient pumping technique is reported whereby 5‐J 200‐kW CO2 laser pulses have been produced in a 3‐in.‐diam, 8‐ft discharge tube. This device, operating at repetition rates of 35–100 per second, 210 W maximum average power. Similar devices 1‐in. through 6‐in. diameters indicate that, unlike continuous‐wave lasers, this pulsed system may be extended least to diam and/or total pressures excess 60 torr, without severe loss plasma uniformity. Preliminary scaling experiments that further increases peak and power might achieved.
