摘要
用三只 QCW- 6 0 0 W激光二极管侧面抽运 Nd:YAG激光器 ,在重复频率为 2 0 0 Hz,单脉冲注入能量为 2 70 m J条件下 ,实现了 2 9.7m J,TEM0 0 模调 Q激光输出 ,M2 =1.12 ,脉宽 6 .4 ns,光 -光转换效率 11% ,斜效率 16 .5% ,输出能量不稳定度 1.14%。通过 KTP晶体腔外倍频 ,获得了单脉冲能量 16 .8m J,脉宽 5.6 ns的绿光输出 ,倍频效率 56 .6 %。
A laser diode array side pumped high repetition rate, Q switched, TEM 00 mode Nd∶YAG laser is reported. With about 270 mJ pump energy, an energy of 29.7 mJ, pulse width of 6.4 ns TEM 00 mode laser output at 200 Hz repetition rate is obtained, slope efficiency is about 16 5%. By using a KTP as a frequency doubling crystal, an energy of 16.8 mJ, pulse width of 5.6 ns green output is achieved, optical optical efficiency is 56 6%.
