Abstract

The use of null optics is proposed as a new concept for the precise alignment of a confocal unstable resonator. The characteristics of the proposed null optics are investigated and analysed with the designed null lens for a real confocal unstable resonator of which the length is 3.5 m. As a result of the analysis, the pupil map data are shown about the despace error of 1.0 mm and tilt error of 1.0 mrad.

공초점 불안정형 공진기의 광학 정렬을 정밀하게 수행할 수 있는 새로운 개념의 null 렌즈 광학 정렬 방법을 제안하였다. 제안된 정렬 방법은 3.5 m 공진기에 적용하여 민감도 분석을 통해 실용성 여부를 판단하였으며, 공진기의 길이 변화가 1.0 mm 발생하였을 때와 반사경이 광축에 대하여 1.0 mrad 기울었을 때에 대한 pupil map 분석 데이터를 제시하였다.
