Abstract

Parameters of output diffraction-limited beam from copper vapor laser are investigated for different unstable resonators: self-imaging, self-filtering and modified self-filtering. Three types of intensity distribution (uniform, Gaussian and Bessel) in near-field (output beam) and far-field (focal plane) zones are considered with 20 mm active medium diameter. Divergence of these beams depends on phase and amplitude distortions by active medium gain saturation. Angle beam position dependencies are considered versus position of more curves mirror and field-limiting aperture of unstable resonators.
