Efficient one-way cleanup of laser beams can be accomplished by holographic matched filtering. Severe amplitude and phase distortions, such as those caused by passage through multimode fibers or ground-glass diffusers, can be compensated for, with theoretical efficiencies of the order of 50% for light in a single state of polarization. Experiments have confirmed the improvement in beam quality.
