利用频闪阴影成像系统，观察和研究了在水、乙醇和正丁醇三种液体环境中脉冲激光烧蚀水下目标时产生的空化气泡的生长和破裂。捕获了气泡体积最小时气泡破裂最后阶段的瞬态图像。乙醇和正丁醇受到空化诱导反应的影响，产生气体产物，阻碍气泡的内爆破裂。相比之下，激光在水中产生的空化气泡在崩溃的最后阶段达到最小的半径，导致局部温度和压力的急剧增加，这可以驱动潜在的第二次蚀刻。我们的研究结果强调了液体的化学效应对空化气泡内爆坍缩的作用，为空化相关现象和液体辅助激光加工提供了更深入的理解。
We observe and study the growth and collapse of cavitation bubbles generated during the pulsed laser ablation of submerged targets in three liquid environments, water, ethanol, andn-butanol, utilizing a stroboscopic shadowgraphy system. The transient images of the final stage of bubble collapse when the bubble volume is at a minimum are captured. Ethanol andn-butanol are subject to cavitation-induced reactions, which produce gaseous products that hinder the implosive collapse of the bubbles. In contrast, laser-produced cavitation bubbles in water achieve the smallest radii at the final stage of collapse, resulting in a sharper increase in localized temperature and pressure that can drive a potential second etching. Our results emphasize the role of the chemical effects of liquids on the implosive collapse of cavitation bubbles, providing a deeper understanding of cavitation-related phenomena and liquid-assisted laser processing.
