Very high energy SBS phase conjugation and pulse compression in fluorocarbon liquids

An optical phase conjugation and laser pulse compression of laser light via stimulated Brillouin scattering at high energy are investigated. SBS operation at high-energy and high average power in fluorocarbon liquids is clarified. Fundamental nonlinear and SBS optics data on particle-free Fluorinert liquids are presented. High capacity SBS cells filed with particle-free Fluorinert liquids were used to demonstrate a very high energy SBS mirror in recent experiments at GEKKO XII laser facility. The pulses of energy as high as 73 Joules were phase conjugated using a SBS phase conjugating mirror. High energy SBS laser pulse compressor was operated at the level 30 Joules. Laser pulse with duration 13 ns FWHM was compressed to 0.6 ns with a high SBS internal efficiency.
