We present theoretical and experimental studies of the process of two-wave mixing of broadband radiation in BaTiO3. We show that the energy exchange in such a process can be calculated on the basis of a system of coupled-wave equations in which phase-mismatch diffraction processes are taken into account. Good agreement of the model predictions and measurements performed with a variable-bandwidth Ti:sapphire laser is reported. Reasonable amplification of light with a FWHM spectrum of as much as 10 nm is reported in a standard copropagation scheme; above this value a considerable gain decrease and significant spatial profile changes occur.
