Abstract

It is demonstrated that the emergence of subharmonics during two-wave mixing in a Bi₁₂SiO₂₀ photorefractive crystal under applied alternating electric fields will markedly reduce two-wave gain. The repetition frequency at which the observed drop in two-wave gain appears is correlated with threshold conditions for the subharmonic instability for a wide range of experimental parameters.
