摘要
报道了在Nd:YAG棒和腔镜间插入四分之一波片,或在KTP倍频晶体和腔镜间插入四分之一波片,以及使用交叉双倍频晶体用以抑制二极管泵浦内腔倍频Nd:YAG激光器绿光噪声的实验结果.实验研究表明,使用上述三种方法之一能有效地减小折叠腔内的绿光噪声.用交叉倍频晶体可使噪声减小18%～25%.实验结果与理论一致,对实验中一些问题和值得进一步改进的地方也进行了讨论.
Abstract
Experimental results of green noise suppression in a diode-pumped intracavity-doubled Nd:YAG laser by inserting a QWP between the Nd:YAG rod and mirror, or between the KTP frequency doubler and mirror,and using two cross-doubled crystals are presented. It is shown that the green noise in a folded resonator can be effectively reduced if one of the above methods is used. The introduction of two cross-doubled crystals has reduced the noise by 18%～25%.The experimental results are consistent with theoretical predications.Some problems in the experiment and further improvements are discussed.
