| Abstract: | A mathematical model based on the energy absorption mechanism of laser-plasma interaction is established.And PIC method is used to investigate the energy absorption mechanism when a non-uniform short-pulsed laser irradiation to the uniform distribution of dense plasma.J×B heating,resonance absorption and vacuum heating are studied in order to find the best energy absorption mechanism for numerical simulation of laser plasma direct deposition shaping. |
