摘要
观察了用LD泵浦Nd∶YVO4 晶体 ,用Ⅱ类临界位相匹配KTP晶体腔内倍频的全固态绿光激光器的噪声特性 ,指出绿光噪声主要来自于倍频晶体内不同纵模的相互耦合。分别采用谐振腔内插入布氏片和采用Ⅰ类位相匹配BBO晶体腔内倍频 ,均实现了连续绿光的低噪声稳定输出。
The noise characteristics of LD-pumped Nd∶YVO 4/KTP(Ⅱ-typed)green lasers were observed in this paper. It shows the no ise has arisen from the coupling of different longitude modes in the frequency d oubler-KTP. At last, two effective methods to eliminate green noise, including inserting a Brewster plate in the resonator of a Nd∶YVO 4/KTP laser, and using type-Ⅰ phase matching BBO as the frequency doubler, were introduced, respectively.
