Abstract

In this paper reported are the experimental results of investigations the compact planar MW excited CO₂-laser. A breadboard model of the planar CO₂-laser excited by a wide-aperture MW discharge of 2x25x250 mm size at a frequency 2.45 GHz was elaborated and constructed. The model includes the following basic components: a primary power supply of a magnetron 2M-130, a microwave waveguide, a planar gas-discharge system, and optical-cavity unit. The optical resonator consisted of two plane mirrors, which were placed 2.5 mm from waveguide. Test experiments were carried out with a repetitive uniform MW discharge with 20 ms pulse duration, 0.4-7.0 kHz repetition frequency at level of the input MW power up to 7 kW per pulse. Average laser output power of 25 W (peak power up 580 W) and operating efficiency of 13% at gas pressure of 30 Torr were obtained without optimization of all laser parameters.
