Abstract
We initially study a peak of the photorefractive two-wave mixing gain which appears for a particular frequency of a sinusoidal applied electric field. The optimization of the process by applying periodic pulsed electric fields leads to a considerable rise of the two-wave mixing gain. The authors demonstrate that the gain reached with this technique is higher than the maximum gain obtained with usual enhancement techniques. Effectively, with a Bi12GeO20:Fe sample, a gain of 10 cm-1 is obtained, compared to 2 cm-1 in the same crystal with the other techniques.
