Numerical study of phase conjugation in stimulated backscatter with pump depletion
Technical Report
·
OSTI ID:6876698
Two dimensional numerical simulations are presented of phase conjugation in stimulated backscatter of a focused aberrated 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 approx. = 90%. In spite of such structure, the backscatter was able to reproduce a rough image of large scale modulation in the incident beam.
