| Abstract: | In this paper, the interaction of femtosecond laser pulses with droplets microplasma at the intensity of 1016 W/cm2 is theoretically studied. Laser absorption, suprathermal electron generation, and second harmonic generation are discussed. Using an analytical model and a 2D particle-in-cell code, we find that the dominated mechanism is resonant absorption in the interaction of femtosecond laser pulses with droplets for the misrospherical geometry. |
