초록

반도체 레이저로 펌핑하는 Nd:YAG 레이저의 내부 발생형 제2차 고조파 발진 문턱 근처에서의 출력 특성을 조사하였다. 라미나 상태에 대한 분석을 통하여 제2차 고조파가 on-off간헐성을 통하여 발진한다는 것을 확인할 수 있었다. 이러한 간헐적인 특성은 비율 방정식을 이용한 수치해석에서도 볼 수 있었다.

We have investigated the lasing characteristics of intracavity second harmonics of a Nd:YAG laser pumped by a laser diode. Through the analysis of the scalings of laminar phases, we verify that the second harmonics are generated through on-off intermittency. The intermittent behavior can be reproduced by a numerical simulation with rate equations.
