Abstract
We propose a Yb:YAG laser Q-switched by a semiconductor saturable absorber and a laser output coupler composed of a polarizer and a quarter-wave plate, and we investigate the output characteristics of the proposed Q-switched laser. We show that the laser power can be varied by rotation of the quarter-wave plate.
