Abstract

본 발명은 제2고조파 발생 장치 조립체에 관한 것으로서 편광 소자의 자세 교정이 용이한 제2고조파 발생장치 조립체에 관한 것이다. 본 발명 제2고조파 발생 장치는, 펌핑 레이저 발생부와, 펌핑 레이저 발생부로부터의 레이저를 후술되는 공진 장치로 접속시키는 포커스 렌즈계, 그리고 레이저 광의 광학적 공진 장치를 갖추며; 공진 장치의 내에는 구면 접촉 회전 구조에 의한 3차원적인 플레이트 자세 교정 장치가 마련되어 있다. 이에 의하면, 고정밀도의 광학적 자세 정렬이 요구되는 브루스터 플레이트의 설치가 매우 용이하게지게 된다. 이와 같이 되면, 블루스터 앵글의 오차에 의한 광학 손실이 억제되어 최종적으로는 제2고조파 발진을 위한 비선형 단결정 소자에 대한 기본파의 주입이 극대화되고 따러서 고출력의 제2고조파를 얻어낼 수 있게 된다.The present invention relates to a second harmonic generator assembly, and more particularly to a second harmonic generator assembly for easy posture correction of a polarizing element. The second harmonic generator according to the present invention includes a pumping laser generator, a focus lens system for connecting the laser from the pumping laser generator to a resonator described later, and an optical resonator for laser light; The three-dimensional plate attitude correction apparatus by spherical contact rotation structure is provided in the resonator apparatus. This makes it very easy to install the Brewster plate, which requires high precision optical posture alignment. In this case, the optical loss due to the error of the bluester angle is suppressed, and finally, the injection of the fundamental wave into the nonlinear single crystal element for oscillation of the second harmonic is maximized, thereby obtaining the second harmonic of high power. .
