摘要：

We report strong competition of intensities between spontaneously emerging beams (subharmonics) and other diffracted beams in two-wave mixing experiments with two frequency-detuned pump beams in photorefractive bismuth silicon oxide. The measurements show that the onset of subharmonics strongly affects the strength of the fundamental component of the primary grating, which caused the subharmonics in the first place. Suppression of subharmonics by vibration of the crystal increased the diffraction efficiency of the fundamental grating component by more than an order of magnitude.
