Two-wave mixing in BTO in the presence of detuning

J. Takacs, David J. Webb, K.H. Ringhofer, L. Solymar

Research output: Contribution to journalArticlepeer-review


The gain of a weak signal beam is measured in the usual two-wave mixing configuration in a photorefractive BTO crystal by varying a set of parameters, namely the applied electric field, the detuning, the beam ratio and the input intensity of the pump beam. All the experimental results are shown to be in good agreement with a theory based on that of Kukhtarev et al.
