Abstract

레이저광빔 발생장치는 레이져 다이오드, 레이저매체, 비선형 광결정요소, 반사거울, 편향거울, 온도제어장치와 케이스를 포함한다. 레이저 다이오드는 적어도 하나의 폄핑레이저광빔을 방사한다. 레이저매체는 레이저 다이오드로 부터의 펌핑레이저광빔에 의해 여기된다. 비선형 광결정요소는 레이저 다이오드로 부터의 펌핑레이저광빔의 출력된 광로에 배치된다. 반사거울은 레이저매체와 비선형 광결정 요소를 갖는 공진기를 구성한다. 편향거울은 공진기로 부터의 광빔의 광로를 편향시킨다. 온도제어장치는 레이저 다이오드와 공진기의 온도를 제어한다. 케이스는 레이저 다이오드, 레이저매체, 비선형 광결정요소, 반사겨울, 편향거울, 온도제어장치를 내장한다.
