【摘要】 研究了端面泵浦Nd∶YAG晶体热透镜效应,提出了一种新的测量热透镜的方法 干涉条纹法,并通过理论估算与用此方法所测的热透镜焦距相比较,表明此方法所测热透镜焦距随着泵浦光功率的增大二者越来越吻合,验证了该方法的可靠性 该方法解决了端泵Nd∶YAG时,由温度梯度,热应力双折射和端面形变所引起的总的热透镜焦距难以测量的问题.更多还原

【Abstract】 The thermal lens effect in the end pumped DPL has been discussed in this experiment. A new method to measure the whole thermal focal lens is found in this paper which is called interference stripe method. The result based this experiment method is agree with the theory result and with the develop of the pump power ,they meet well deeply.更多还原
