Theoretical study on Brillouin-enhanced four-wave mixing with large incident signals

Based on the application demands of high-power laser phase-conjugate systems, the potential of Brillouin-enhanced four-wave mixing(BEFWM) applying in this field is represented. Correspondingly, physical mechanism and output characteristics of BEFWM with large incident signals are studied specially. It is demonstrated that BEFWM’s performances, such as response speed, pulse-shape fidelity and stability, and energy transform efficiency will increase with increasing intensity of the signals.
