摘要: This Letter is the first report of observation amplified reflection and self-oscillation produced by degenerate optical four-wave mixing using a resonantly enhanced Kerr nonlinearity in atomic sodium vapor. Phase-conjugated reflected waves with intensities 100 times greater than input-signal were achieved only 40-kW/cm2 pump intensity.
