초록

반사도 가변형 출력경을 갖는 긴 공진기형 선편광 Yb:YAG 레이저를 제안하고 그 출력 특성을 조사하였다. 반사도 가변형 출력경은 편광 광 분할기와 1/4 파장판로 구성되어 있다. 제안된 레이저 공진기 길이는 약 3.7 m 이다. 제안된 레이저의 기울기 효율은 19%이고 빔질 ($M^2$)는 약 1.2이었다.

We propose a linearly polarized long-cavity Yb:YAG laser with a variable-reflectivity output coupler and investigate its output characteristics. The variable output coupler consists of a polarized beam splitter and a quarter-wave plate. The linearly polarized laser has a long cavity length of about 3.7 m. The slope efficiency of the proposed laser is 19%, and the beam quality ($M^2$) is about 1.2.
