摘要
报道了一种采用双二极管抽运头、电光调Q实现高重频、窄脉宽Nd∶YAG激光输出特性。在重复频率1 kHz,二极管驱动电流65 A,BBO晶体电光调Q条件下,实现了平均功率6.5 W,电光效率10%,脉冲宽度17.25 ns的TEM00模1064 nm激光输出。研究了KD*P及BBO晶体的高重频工作特性,为下一步在高重复频率抽运时获得大能量的高光束质量激光输出奠定较好的基础。
The characteristic of a diode （LD） side-pumped Nd：YAG crystal,electro-optic Q-swtiching with high repetition rates, narrow pulse width and high beam quality is presented in this paper. The experimental results with incident pump current of 65 A, repetition rate of 1 kHz, BBO Q-switching, average power of 6.5 W, electro-optic efficiency is 10% ,pulse width of 17.25 ns ,TEM00 laser is obtained. The characteristic of KD^＊ P and BBO crystal with high repetition rate is studied. The study foundation was built up for the future experiments of high repetition rate, high energy and high beam quality laser.
