Abstract :
Phase matching angles for sum and difference frequency mixing in a 7% MgO:LiNbO3 crystal of the radiation of a Ti:Sapphire laser and the radiation of 2.2 to 3.4 μm from a Raman shifter are used to determine the refractive indices of the crystal. A dispersion equation accurate in the mid-infrared spectral range as well as in the visible and near infrared range is firstly given. Based on this result the phase matching characteristic of a mid-infrared optical parametric generator using 7% MgO:LiNbO3 crystal is described
