本文采用自行研制的传感器研究了在不同能量的脉冲激光作用下，水中靶材所受的力学效应。
A novel optical sensor is developed to investigate the mechanical effects during pulsed laser ablation of metals in water at different pulse energies.
实验发现，在脉冲激光作用下，水中靶材依次受到激光烧蚀压力和射流冲击力作用，且射流冲击力是造成靶材破坏的主要原因。
Furthermore, the experimental results show that underwater targets are impacted in turn by laser-generated ablation force and high-speed liquid-jet impulse induced by bubble collapse.
