Abstract
We present measurements of the steady-state two-wave mixing gain in photorefractive InP:Fe crystals cooled with a Peltier cell, as a function of fringe spacing, external d.c. field and pump intensity. High gain values (up to 11.4 cm-1 at 10 kV/cm) can be obtained with an accurate control of pump intensity and sample temperature. Such behaviour can be explained with a new model which predicts a new resonance mechanism yielding a strong en-hancement of the gain for a critical intensity.
