Effect of laser-pulse-shape on the transference of laser energy into the energy of fast ions in radiation pressure dominant regime
The effect of laser-pulse temporal-profile on the transference of laser energy into the energy of fast ions when the radiation pressure is dominant, has been studied. The laser temporal profiles considered are Lorentzian, hyperbolic secant, and Gaussian. The numerical results are compared for different temporal profile of the laser pulse. It is found that the Lorenztian pulse is more effective to impart kinetic energy to the ions in comparison to Gaussian or hyperbolic secant laser pulse.
