摘要
采用自行研制的高灵敏度的光偏转测试系统,测量了激光泡在不同激光能量作用下前三次脉动空泡的最大半径,结果表明在作用相同激光能量的情况下,随着脉动次数的增加,最大泡半径依次减小;对应于同一次脉动,随着激光能量的增加,最大泡径呈增加趋势;在此基础上分析了各次脉动过程中空泡泡能衰减的规律,取得了理论和实验在误差范围内相一致的结果。
By means of a high-sensitive fiber-optic sensor, which was developed in Nanjing University of Science ＆ Technology based on optical beam deflection, the maximum radii of a laser-induced cavitation bubble in the vicinity of an aluminum target in water was carefully measured during the three oscillating cycles. It indicates that following the increase of oscillating cycles, the maximum bubble radii decrease, and that corresponding to the same order of the cycles, the maximum bubble radii increase with increase of irradiation lager energy. The theoretical and experimental results are in agreement within reasonable deviations.
