Paper Abstract

We report on high beam quality diode end-pumped Q-switched Yb:YAG laser with elliptical cavity mode configuration operating at 1÷100 kHz repetition rates. Laser coupler transmittance optimization in CW is carried out. Measurements of thermal lens in laser active element by means of Shack-Hartmann wavefront sensor are presented. It is shown that thermal lens in such laser is highly astigmatic. We have also measured laser beam quality parameter M2, which does not exceed 1.2 value at the highest pump power.
