TLDR
In this article, the authors investigated the dependence of heat transfer on a wide range of film materials and film thicknesses and found that the dependence on these parameters is much weaker than is predicted by heat transfer estimations commonly used to describe the interaction of laser irradiation with unconfined bulk-solid surfaces.Abstract:
Investigation results on stress waves generated by Q-switched ruby laser irradiated thin metal films under confinement, studied over a wide range of film materials and film thicknesses, are reviewed. The results indicate that the dependence on these parameters is much weaker than is predicted by heat transfer estimations commonly used to describe the interaction of laser irradiation with unconfined bulk-solid surfaces.read more

Physical study of laser-produced plasma in confined geometry
TL;DR: In this article, the authors studied the physical processes involved in laser-produced plasma in confined geometry, and showed that a large fraction of the absorbed laser energy (80% to 90%) is used for the ionization of the medium in these conditions of irradiation.

Generation of shock waves by laser‐induced plasma in confined geometry
TL;DR: In this article, the dielectric breakdown of a neodynium glass laser at 1.06 μm and pulse width of 3 and 30 ns was studied. And the authors showed that the use of a short rise-time laser pulse is the only way to reduce the effects of the breakdown and to obtain much higher pressure shock waves.

Piezoelectric Current from Shock‐Loaded Quartz—A Submicrosecond Stress Gauge
TL;DR: The results of an extensive experimental study of the current from shockloaded X-cut quartz disks are reported for shock stress up to 50 kbar as mentioned in this paper, where the current amplitude and its time dependence are functions of the dielectric, piezoelectric and mechanical properties of quartz under shockloading conditions.
