Abstract
Degenerate four-wave mixing in a two-level saturable absorbing medium is calculated on and off resonance for arbitrary input laser intensiti es and absorption coefficients. The maximum efficiency occurs at laser intensities higher than saturation in an optically thick medium. On r esonance, the maximum efficiency can approach approximately 4%, and it can be as large as 25% when the laser is tuned off resonance.
