Numerical Study of Phase Conjugation in Stimulated Backscatter with Pump Depletion.
Abstract
Two dimensional numerical simulations are presented of phase conjugation in stimulated backscatter of a focused abberrated beam, including the effects of pump depletion. In all cases, pump depletion significantly improved the conjugation fidelity H. As expected, the far field distribution of light scattered back through the aberrator exhibited a prominent axial spike closely matching that of the incident beam; however, the near field distribution had large and rapid spatial inhomogeneities, even for H approximately 90%. In spite of such structure, the backscatter was able to reproduce a rough image of large scale modulation in the incident beam.
