    Amplification of laser beams via parametric instabilities in plasma (stimulated Raman and Brillouin scattering) has been proposed a number of times [1-5], but came into its own only relatively recently [6-19]. This has been accompanied by an increasing effort to optimize the parameters for the interaction via numerical simulations [20-26].

  2. It is shown here that Brillouin amplification can be used to produce picosecond pulses of petawatt power. Brillouin amplification is far more resilient to fluctuations in the laser and plasma parameters than Raman amplification, making it an attractive alternative to Raman amplification. Through analytic theory and multi-dimensional computer simulations, a novel, well-defined parameter regime ...

    Brillouin amplification in plasma is more resilient to fluctuations in the laser and plasma parameters than Raman amplification, making it an attractive alternative to Raman amplification. In this work, we focus on high plasma densities, n0>ncr/4 , where stimulated Raman scattering is not possible and laser beam filamentation is the dominant competing process. Through analytic theory and multi ...
