| Abstract: | The aim in this paper is to design a laser system,which can achieve high stability,narrow pulse width and high peak power output at 532nm.firstly,the LD side-pumped Nd：YAG pulse laser at 1064nm was achieved by the simple and compact flat-flat cavity with electrooptical Q-switched technology,secondly,the pulse laser was extra-cavity frequency-doubled by KTP.When the cavity length is 164cm,repetition rate is 200Hz,the pumped current is 70A,and pump width is 230μs,the single green pulse output energy is 1.68mJ,the pulse width is 8ns,and the peak power is 210KW,and the efficiency of frequency-doubling is about 17.98%.Experimental results show that the pulse width is relatively narrow,peak power is high and the stability of laser is relatively high. |
