Bi. Sturman et Sg. Odoulov, PHYSICAL ORIGIN OF MIRRORLESS PARAMETRIC OSCILLATION IN BATIO(3), Journal of the Optical Society of America. B, Optical physics, 11(9), 1994, pp. 1700-1707
Mirrorless oscillation is observed in BaTiO3 when the sample is pumped
by two nearly counterpropagating light waves, each containing an ordi
nary and an extraordinary component. We present a theoretical descript
ion of this effect and derive the threshold conditions in the undeplet
ed pump approximation. The theoretical predictions, especially the fre
quency detuning of the oscillation waves with respect to the pump wave
s, are confirmed by our experiments.
