Abstract:
The effectiveness of laser beam cleanup with photorefractive two-beam coupling is evaluated. We compare the measured effectiveness of the method with that of spatial filtering and find that the method works well for a highly aberrated beam approximately 700 times diffraction limited, whereas for moderately aberrated beams the effectiveness of the method is the same as that of spatial filtering.
