Parametric Amplification of Laser Light by Stimulated Brillouin Scattering (SBS) in Plasma
N. Gupta
The idea recommends a new class of optical amplifiers based on parametric a parametric instability in plasma known as stimulated Brillouin scattering (SBS). In SBS there is an exchange of energy between electromagnetic radiation and an ion acoustic wave (IAW) propagating through plasma. IAWs in plasmas are analogous to sound waves propagating through gases or solids. The proposed amplifier consists of two stages. In the first stage the input optical signal is amplified through stimulated emission in a gain medium. In the second stage this amplified signal undergoes further amplification parametrically through the process of SBS.
