Abstract

본 발명은 종래의 수동형 모드로킹 광섬유 레이저 구도가 가지는 초단 광펄스 생성 구도의 장점과 일반적인 능동형 레이저가 가지는 반복율 변환 특성 및 광펄스의 동기화가 쉬운 점을 동시에 활용하여, 반복율 변환 특성과 용이한 펄스 동기 특성을 가지면서 초단 광펄스를 얻을 수 있는 구도에 관한 것으로, 두개의 루우프가 광커플러로 연결된 레이저 구조를 하며 한쪽 루우프는 기존의 수동형 모드로킹에서의 비선형 증폭 루우프로 구성되고 다른쪽 루우프에는 광변조기와 광이득을 포함하여 능등형 모드로킹을 유도하며 시간지연 선로를 이용하여 레이저 발진 반복율을 조절할 수 있도록 구성되어, 앞으로 고속 시간분할다중 광통신과 광프로세서, 초고속 광현상분석에 고속 초단 광펄스의 활용은 가능할 것이다.
