A New Method Called Interference Stripe Method For Measuring the Whole Thermal Focal Lens In LD End Pumped Nd:YAG Crystal
干涉条纹法测量LD端面泵浦Nd∶YAG热透镜焦距

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.
