Abstract

Temporal, spatial and energy characteristics of copper vapor laser with confocal unstable and self-filtering unstable resonators are presented. Conditions for obtaining diffraction-limited divergence of radiation were founded experimentally when light passed only one round-tripp for different magnifications of resonator, diameters of active medium and field-limiting aperture. Comparison is carried out for output characteristics of oscillator-amplifier system with different types of oscillator resonator. Application of this system to laser precise machining is mentioned.
