Abstract:The mechanical effects of laser-metal interaction underwater at different incident laser energies are investigated in detail using a new force sensor based on optical beam deflection.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 collapes.Furthermore,the amplitudes of the three forces are increased with the increase of laser energy.According to the ablation force detected in experiment and the relationship between laser intensity and ablation pressure,the value of liquid-jet impact can be easily obtained.In addition,the bubble collapsing duration,the maximum bubble radius,the liquid-jet velocity and bubble energy at different laser energies can also be attained by the experimental results,which are valuable in the relevant research fields.
Keywords:cavitation bubbles  liquid-jet impact  laser ablation  force sensor
