激光带宽对等离子体中受激拉曼散射不稳定性的抑制效应
摘要
The suppression effects of laser bandwidth on stimulated Raman scattering (SRS) instability in underdense plasma are studied by one-dimensional particle-in-cell (1D PIC) simulations. By changing laser and plasma parameters, it is shown that the linear growth of SRS can be suppressed considerably, provided the laser bandwidth is much larger than SRS linear growth rate. Simulations also show that by choosing the proper frequency modulation parameters or decreasing the linear growth rate of SRS, the inhibitory effects become more obvious. However, the laser bandwidth can only increase the timeduration for linear growth but cannot diminish the instability completely.
