摘要

Using a new method for measuring photorefractive two-wave mixing gain, we present the first experimental demonstration of nonreciprocal energy transfer during two-wave mixing under an external magnetic field. The nonreciprocal energy transfer is observed with mixing gains approaching 164 cm$+$MIN@1$/ exhibiting the characters of nonlinearity and saturation. A simple model of negative differential mobility and ultra fast carriers lifetime was proposed to explain these results.
