title: Nonlinear optics with a diode-laser light source.
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/cm(2), we observe diffraction efficiencies of ~10(-4), corresponding to an effective nonlinear coefficient of chi(3)~6 x 10(-2) esu.
