Abstract :
This work aims to decrease the beam divergence of a CW Nd:YAG laser without serious output power losses. An unstable resonator was used consisting of two HR plane mirrors and internal output mirror with feedback hole. In spite of decreasing of the output laser power on 40% the brightness increases in 30 times.
