Abstract

We have investigated a nondegenerate transient four-wave mixing scheme that uses the coupled absorption and emission resonances in a four-level system. Strong frequency-shifted signals can be produced if high initial gain is present. In addition, the medium’s recovery time can be significantly decreased owing to the presence of stimulated emission, which occurs simultaneously with signal generation. Dyes are likely medium candidates.
