摘要
红光低噪声激光器在很多方面有着重要的应用,实现低噪声的方法很多,如环形腔法、扭摆模腔法、标准具法等等,以上方法要么结构复杂要么损耗很大,不适合小型化,产品化。研究报道了一种利用Nd:YVO_4激光器的偏振特性和Ⅱ类临界相位匹配LBO作为倍频晶体构成双折射滤光片的方法实现低噪声红光激光输出,在注入泵浦功率2W的情况下获得61mW的671nm低噪声红光输出,光一光转换率3%,该结构简单、紧凑,适合用于中低功率激光器。
Low noise 671nm red laser was used in many field. There are many configuration can achieve low noise red laser, such as ring cavity laser, twist mode cavity laser, put a etalon in the laser cavity and so on, but there are many disadvantage in the setup of above. A kind of birefringent filter configuration was achievement by type Ⅱ critical phase-matched LBO and Nd：YVO4 crystal. When the pumping power input into Nd：YVO4 is 2W,61mW 671nm red laser with low noise was obtained. This configuration is very simple, compact which is suit for medium and low power laser.
