Abstract
We propose a theory of the instability of the space-charge field induced in a semiconductor by the movement of light fringes against subharmonic gener ation. A crucial element of this theory is taking into account three-dimens ional perturbations and higher spatial harmonics of the space-charge field. It is shown that, irrespective of fringe contrast and velocity, the strong est instability corresponds to the excitation of subharmonics that are not split in the transverse direction. The theory is applied to experimental da ta on subharmonic generation in sillenites. (C) 1999 Optical Society of Ame rica [S0740-3224(99)01507-6].
