摘要
In this paper. the interaction of femtosecond laser pulses with droplets microplasma at the intensity of 10(16) W/cm(2) 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.
