Abstract: A study of the gas dynamics of the vapor plume generated during laser ablation was conducted including a counterpropagating internal shock wave. The density, pressure, and temperature distributions between the external shock wave front and the sample surface were determined by solving the integrated conservation equations of mass, momentum, and energy. The positions of the shock waves and the contact surface (boundary that separates the compressed ambient gas and the vapor plume) were obtained when the inciden… Show more

“…By comparing data obtained from time-and space-resolved UV/visible emission spectroscopy and Langmuir probe measurements with theoretical models of plume expansion in gas [8,9] it is possible to gain some understanding of plume dynamics. The influence of doping with Mg, Ga and Er on electron temperature and plume stopping distance was also investigated.…”

“…The energy conversion from the laser to the kinetic energy of the ablation plume in a rare-gas atmosphere has been measured experimentally. 18,19 The laser pulse energy, E L , was 30 mJ and the laser fluence was 42 J/cm 2 at maximum. It is difficult to extrapolate the energy conversion efficiency from a moderate E L to a higher E L of the order of kJ.…”

“…Despite the efforts of computational [11][12][13][14] and experimental [15][16][17][18][19] studies to date, the prediction of the global energy balance remains difficult. The energy conversion from the laser to the kinetic energy of the ablation plume in a rare-gas atmosphere has been measured experimentally.…”
