摘要
实验研究光偏转检测原理和实验装置，并用此装置测得黄铜、铝、４５号钢的激光烧蚀阈值分别为０．０１８５ＧＷ／ｃｍ２、０．０１３３ＧＷ／ｃｍ２、０．０１９５ＧＷ／ｃｍ２。
In this paper the principle of laser beam deflection method and its experimental setup are described. The ablation threshold for Cu, Al and, 45# Steel have been determined to be about 0.0185GW/m2, 0.0133GW/m2 and 0.0195GW/cm2 respectively
