Paper Abstract

A thermal compensation method (based by using an adaptive optical mirror as the rear mirror of the resonator) was studied in order to improve the quality of laser beam obtained from different super-Gaussian unstable resonators. For a Nd:YAG laser rod the free-running regime was analyzed at 1 Hz, 5 Hz and 10 Hz rates of pumping and different values of pumping energy. Laser pulses with 250 microsecond(s) duration were used. At 5 Hz and 10 Hz rates of pumping the beam quality was maintained at the 0.8 mm mrad value.
