Abstract

It is shown that signal-beam fidelity in degenerate four-wave mixing, which is affected by the finite beam widths of the pump beams, may be largely restored over a wide range of spatial frequencies. The technique consists of focusing the probe beam into the mixing cell. This permits restoration of up to about 90% of the principal distortion effect.
