We investigate theoretically and experimentally multistep parametric processes in broadband optical parametric generators based on periodically poled 1 mol % MgO-doped stoichiometric LiTaO3. We demonstrate that parametric collateral processes may deplete or enhance spectral portions of the optical parametric generation output, depending on pump pulse duration.
