Abstract

The peak power and gain available from the RF excited planar waveguide CO₂ laser has been enhanced for pulses in the 10 to 100 µs range at pulse repetition rates up to 4 kHz. The specific peak power output for unit electrode area has been enhanced to a value of 240 kW.m^-2. Relative to cw, the small signal gain coefficient has been pulse enhanced by a factor of 7 to 2.5 m^-1.
