| Abstract: | 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. |
