In a degenerate four wave mixing system, the phase conjugate signal from a transmission
grating recorded in a Bi 1 2 SiO 2 0 crystal is measured at various temperatures and the …

A simple model of the effect of optical activity on two-wave mixing coupling constants in Bi

We study the process of two-wave mixing (TWM) in optically active, electro-optic, and elasto-
optic BSO and BTO crystals. We calculate the TWM gain for arbitrary crystal cut and optimize …
