摘要：

We demonstrate the simultaneous generation of sum, difference, and harmonics of two laser frequencies (which can be tunable) by spread spectrum phase matching in a nonlinear Sr0.61Ba0.39Nb2O6 crystal. The phase matching is obtained by inducing in the crystal domain gratings with broadband periodicity. Conversion efficiencies up to approximately 1% were observed. We also give a calculation that shows the effect of the spread spectrum domains on the mixing.
