Repetitively pulsed slab waveguide rf-excited CO 2 laser

Abstract

Research and development of pulsed-repetitively slab RF-excited CO2 laser is presented. The experiments were carried out for two modes operation: meander mode (duty factor 50%) and pulse repetition mode at S = 12.5%. The range of 240 ÷ 4000 Hz of pulse repetition frequency was used. Pulse power about 400 W for meander mode and up to 700 W for the second mode have been obtained. Input power, radiation pulse shape and output beam divergence were measured.
