![]() ![]() Hence, a great thickness of water is used instead of the extensively used thin water layer. The proposed configuration mainly consists of the usage of a water tank. This can enlarge the range of applications of laser shock such as the range of treatable materials (very high strength materials) or facilities’ costs since neither vacuum nor heavy laser systems will be needed to reach these levels of pressure. Using this new configuration, pressures above 12 GPa have been reached for the first time in confined regimes. ![]() The authors present a new configuration for laser-induced plasmas in confined regimes for a 10 ns-range laser pulse in the green wavelength (532 nm) that repulses the breakdown threshold above 20 GW/ cm 2 compared to 8 GW/ cm 2 as generally indicated in previous works.
