Abstract
The range of operation of a CO2 laser in pulses due to passive Q-switching is extended to high pressures of the absorber (200–800 Torr) and high intensities of the irradiation in the absorption cell (1 kW/cm2 average power). This extension may be applied to high power CO2 lasers. The experimental results indicate that thermal saturation is involved in the Q-switching. The theory of passive Q-switching is extended to include this effect and is compared with the experimental results.
