摘要

研究了波长为 1064 纳米的纳秒和皮秒激光脉冲照射水所引起的光学击穿。实验证明，光学击穿中心既包括溶解气体的单个纳米气泡，也包括由这些纳米气泡形成的簇。研究发现，纳米气泡簇光学击穿的第一阶段意味着这种簇的诱导光学凝聚（坍塌）和宏观气泡的形成。纳秒和皮秒脉冲的实验结果与之前建立的理论模型的预测结果非常吻合。

Experimental Proof of the Effect of Induced Optical Coalescence of Bubston Clusters at Water Breakdown Induced by Picosecond and Nanosecond Laser Pulses

The optical breakdown in water, caused by irradiation with nanosecond and picosecond laser pulses at a wavelength of 1064 nm, has been studied. It is proven experimentally that optical breakdown centers are both individual nanobubbles of dissolved gas and clusters formed by these nanobubbles. It is found that the first stage of optical breakdown on nanobubble clusters implies induced optical coalescence (collapse) of such a cluster and formation of a macroscopic vapor bubble. The obtained experimental results for nanosecond and picosecond pulses are in good agreement with the predictions of the previously developed theoretical model.
