Abstract
The stationary solution is obtained for the photorefractive subharmoni c gratings excited in crystals of the sillenite family by a standing l ight interference pattern and an applied ac electric field. We show th at the main subharmonic with doubled spatial period may become unstabl e against excitation of the subharmonic with quadrupled spatial period . The threshold condition for this bifurcation is found. [S1050-2947(9 8)05808-9].
