摘要：

We report photorefractive two beam coupling gain coefficients as high as GAMMA = 19 cm-1 and net gains of GAMMA-alpha = 14 cm-1 in InP:Fe at around 970 nm. This enhancement was achieved by combining band-edge resonant nonlinearities with a second resonant enhancement derived from the bipolar transport in this material. Measurements of gain as a function of pump intensity, applied field, grating spacing, wavelength, and temperature are presented. No moving gratings were required.
