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.Keywords: Yb:YAG laser, Saturable absorber, Q-switchingOCIS codes: (140.3540) Lasers, Q-switched; (140.3615) Lasers, ytterbium; (140.3480) Lasers, diode-pumped
