Theoretical analysis of a Brillouin switch for amplifier decoupling and prepulse suppression in short-pulse high-power laser systems
A switch suited for high-power amplifier chains emitting nanosecond pulses is investigated theoretically. It is based on a two-step Brillouin backscattering process. Gases such as N(2) or SF(6) at high pressure are used as the scattering medium. The transmission efficiency is about 50%. The limitation is mainly due to gas breakdown. The capability for amplifier decoupling and prepulse suppression is excellent. Strong pulse steepening favours the generation of ultra-short laser pulses.
