Abstract

비색수차 사분 파장판을 가진 환경적으로 안정된 광섬유 모드록 레이저 발생 장치가 개시된다. 광섬유부는 편광 유지 광섬유로 이루어지며, 일단부로부터 타단부 방향으로 제1영역에는 브래그 격자가 형성되어 있고, 나머지 제2영역에는 코어에 이득물질이 도핑되어 있다. 광결합부는 펌프 레이저를 입력받아 광섬유부의 일단부로 제공하고, 광섬유부로부터 입력되는 레이저를 출력한다. 렌즈부는 광섬유부의 타단으로부터 출력되는 광을 평행광으로 변환한 후 일정한 영역에 집중시킨다. 편광조절부는 렌즈부에 구비되는 렌즈들 사이에 배치되며, 각각의 고속 축이 서로 직교하도록 적층된 두 개의 사분 파장 결정판으로 이루어진 비색수차 사분 파장판이 광섬유부의 고속축 또는 저속축에 대해 각도조절되어 레이저의 모드록킹과 스펙트럼 필터링 대역폭을 제어한다. 포화흡수부는 제2렌즈부를 통과한 광을 포화흡수 반사시켜 모드록킹을 유발한다.
