Dynamic Behaviours of Shock Wave Produced by XeCl Laser-Induced Breakdown Plasma in Atmospheric Air

Shock wave confinement-induced plume temperature increase in laser-induced breakdown spectroscopy

Numerical simulation of laser–induced breakdown in air

Numerical simulations of laser energy deposition in quiescent air and in isotropic turbulence are conducted. The flow field is classified into three phases: shock formation, shock propagation and subsequent collapse of the plasma core. Each phase is studied in detail. Vorticity is found to be generated in the flow at short times due to baroclinic effects and at long times due to rolling up of t...

Time-resolved studies of Nd:YAG laser-induced breakdown. Plasma formation, acoustic wave generation, and cavitation.

The use of high intensity ultrashort pulsed laser radiation to produce optical breakdown is an important approach for the surgical treatment of intraocular structures. We have investigated the transient properties of Nd:YAG laser induced breakdown in a saline model using time-resolved spectroscopic techniques. Spatially resolved pump and probe techniques are applied to study the dynamic behavio...
