Abstract
It is shown that counterpropagation of two light beams in a photorefra ctive medium can be unstable against spontaneous emission of light wav es of the same frequency and polarization traveling at small angles. T he mechanism of the instability is based on the buildup of a set of sp atial reflection gratings. The threshold thickness and the correspondi ng emission angle are found. Results of the theory are applied to inte rpretation of existing experimental data.
