Paper Abstract

A compact size high power Q-switched CO2 laser has been developed using a combination of intense pulsed radio frequency discharge excitation and a high speed rotating Q-switch chopper. Performance characteristics have been investigated in detail as functions of input discharge energy, Q-switching speed, pulse repetition frequency, laser gas composition and oscillation wavelength. Typical output characteristics for free running oscillation wavelength (10P20) show -500 kW pulse peak power, 170 mJ pulse energy, 250 ns pulse duration (FWHM) and 680 W average power at 4 kHz repetition frequency.
