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.

편광기와 1/4 파장판을 이용한 레이저 출력경을 적용한 반도체 포화 흡수체에 의해 Q-스위칭된 Yb:YAG 레이저를 제안하고 그 출력 특성을 조사하였다. 설치된 1/4 파장판의 회전각을 변화시킴으로써 레이저 출력을 가변시킬 수 있음을 보였다.
