Abstract

에너지 조절이 가능한 단일 편광 모드 잠금 레이저 발생 장치가 개시된다. 본 발명에 따른 단일 편광 모드 잠금 레이저 발생 장치는 포화 흡수부로 기능하는 반도체 포화 흡수 거울(semiconductor saturable absorber mirror : SESAM)에 레이저 광을 집중시키는 렌즈의 초점 거리, 펌프 레이저 광의 파워 및 출력 결합기의 반사도 중에서 적어도 하나를 조절하여 포화 흡수부에 입사되는 레이저 광의 단위 면적당 에너지 밀도로 정의되는 영향도가 포화 흡수부의 반사도가 최대값일 때 포화 흡수부에 입사되는 레이저 광의 단위 면적당 에너지 밀도인 기준 영향도보다 크게 되도록 설정된다. 본 발명에 따르면, 다중 펄스의 형성없이 에너지 조절 가능한 단일 편광 모드 잠금 레이저를 발생할 수 있다.
