Abstract
We report results of cw degenerate four-wave mixing experiments on room-temperature GaAs–GaAlAs multiple-quantum-well material using a commercial semiconductor diode laser as the sole light source. With cw powers of ~3 mW and intensities of ~13 W/cm2, we observe diffraction efficiencies of ~10−4, corresponding to an effective nonlinear coefficient of χ3 ~ 6 × 10−2 esu.
