论文摘要
对于当前最新的Terawatt激光器，血浆中的主要激光散射机制包括向前拉曼散射（FRS），血浆波的激发和自我调节不稳定性（SMI）。使用2D PIC模拟，我们以中低密度等离子体和非相关性激光场在制度中的FRS占主导地位。但是，使用多色激光器具有超过等离子频率的频率$δω>ω_ {\ rm pe} $的使用频率抑制了FRS。然后可以有效地传输激光功率。
For current state-of-the-art terawatt lasers, the primary laser scattering mechanisms in plasma include Forward Raman Scattering (FRS), excitation of plasma waves, and the self-modulational instability (SMI). Using 2D PIC simulations, we demonstrate the dominance of the FRS in the regime with medium-to-low density plasma and non-relativistic laser fields. However, the use of multi-colored lasers with frequency detuning exceeding the plasma frequency, $Δω>ω_{\rm pe}$, suppresses the FRS. The laser power can then be transmitted efficiently.
