In this paper, the authors measured the transient pressure caused by laser ablation of toluene under KrF laser irradiation and compared the results with time-resolved images.Abstract:
Transient processes of laser ablation of a highly laser-absorbing liquid, toluene, were investigated by directly measuring (by using a fast-response pressure gauge) the transient pressure caused by toluene ablation under KrF laser irradiation . The results were compared with time-resolved images . The peak pressure P due to a shock wave decreased slowly with increasing distance d for d=100–1000 μm:P∝d-0.33. By extrapolating P to d=8.9 μm, the optical penetration depth of toluene at λ=248 nm, the estimated initial pressure due to toluene ablation was 65 MPa at 1.0 J cm-2 pulse-1. The estimated initial pressure increased linearly with the fluence. These results help clarify the mechanism of laser-induced backside wet etching.read more

Nanosecond Time-Resolved Observations of Laser Ablation of Silver in Water
TL;DR: In this paper, optical emissions, a shockwave, and a cavitation bubble were generated sequentially from the target surface after laser irradiation and continuous bands were observed, which were probably attributable to bremsstrahlung and/or electron-ion recombination.

TL;DR: In this paper, the authors investigated the partition of laser energy between these channels during breakdown in water, and found that the absorption at the breakdown site first decreases strongly with decreasing pulse duration, but increases again for < 3p s.

Shock wave emission and cavitation bubble generation by picosecond and nanosecond optical breakdown in water
TL;DR: In this paper, the authors used time-resolved photography to measure the position of the bubble front and the bubble wall as a function of time and the photographs were used to determine the shock front and bubble wall velocity as well as the shock wave pressure.

Optical and acoustic investigations of the dynamics of laser-produced cavitation bubbles near a solid boundary
TL;DR: In this paper, the dynamics of laser-produced cavitation bubbles near a solid boundary and its dependence on the distance between bubble and wall are investigated experimentally by means of high-speed photography with up to 1 million frames/s that jet and counterjet formation and the development of a ring vortex resulting from the jet flow are general features of the bubble dynamics near solid boundaries.
