Correction of Phase Distortion by Nonlinear Optical Techniques
Abstract
The main accomplishments of the first phase of the program are listed below: demonstrated complete aberration correction by SBS (Stimulated Brillouin Scattering) for beams aberrated to 35X the diffraction limit; performed detailed photographic measurements to establish spatial distribution of beam profiles to intensities down to about .0001 of peak intensity; established experimentally that the fraction of nonconjugate return when using SBS for correction is below measurement limits; developed systems applications exploiting novel variations of nonlinear phase conjugation techniques in the area of high-power oscillator compensation, master-oscillator power-amplifier train compensation, and systems which require correction for atmospheric turbulence with very high spatial frequency content; and furthered the theoretical understanding of phase conjugation by SBS in waveguides and in nonwaveguide (free space) geometries.
