摘要
对实验研制的高功率、短脉冲强激光冲击处理装置进行了输出特性研究,其输出能量不稳定度和激光脉冲功率不稳定度分别为±3.8%和±6.5%。采用透镜列阵的焦斑均匀化系统使光强分布起伏度达到±12%。并利用新型压电传感器(PVDF压电传感器)对其引发的激光冲击波压力进行了实时测量。
We research the output properties of high po wer, short pulse strong laser shock processing equipment, the output unstable de gree of energy and the output unstable degree of laser pulse power is respective ly ±3.8% and ±6.5%. we adopt focal spot uniformization system of lens array an d make the risen and fallen degree of light intensity only to ±12%. We utilize new type piezoelectricity gauge ( PVDF piezoelectricity gauge) to carry on real- time measurement to laser-induced shock wave pressure.
