Paper Abstract

There are described some constructions and generation characteristics of small–sized sealed–off metal–ceramic CO2-lasers working at super atmospheric pressures with active discharge volumes V1 =18×0.8×0.8 cm3 and V2 =7×0.8×0.8 cm3 and resonator length 20÷46 cm. The main goal of this work was determination of main interrelations between gas discharge parameters, parameters of optical resonator and laser energy per pulse and laser pulse duration. There are achieved radiation pulses with a maximum energy per pulse up to 50÷150 mJ and with minimal durations 5÷8 nanoseconds at pulse repetition rates up to 20 Hz.
