Abstract
AbstractA novel composite optical phase conjugator that combines Brillouin-enhanced four-wave mixing (BEFWM) and stimulated Brillouin amplification (SBA) in a compact structure is reported. A phase-conjugate wave seed is generated by BEFWM process with characteristics such as fast response, high conjugate fidelity and stability, then it is magnified by SBA with high energy-conversion efficiency. As a result, advantages of BEFWM and SBS can be realized at the same time. This composite conjugator has potentials for high-peak and high-average power laser applications, especially for short pulse or steep leading-edge pulse laser systems. Feasibility of this BEFWM-SBA mechanism is verified in theoretical simulations and demo experiments.
