激光等离子体诊断用微微秒紫外高功率激光脉冲的产生

氙灯泵浦的可调谐染料激光器锁模脉冲用XeCl准分子激光器泵浦的三级染料激光放大器放大后,经倍频再用XeCl准分子激光器放大,在308毫微米处获得了微微秒高功率激光脉冲输出,其峰值功率可达500兆瓦,功率净增益为200。

Generation of UV picosecond high power laser pulses for laser-produced plasma diagnosis

Mode-locked pulses generated by a tunable flashlamp-pumped dye laser was amplified in three stages of dye laser amplifiers pumped by the XeCl excimer laser, using another XeCl excimer laser to amplify the frequency-doubled pulses, picosecond high power laser pulses were obtained at 308 nm with a peak power of 500 MW, and the net power gain is 200.
