Abstract
In this work we report optical parametric generation in two dimensional, second order periodically poled lithium tantalate crystals. We are particularly interested by angular tuning of the conversion efficiency. We experimentally demonstrate that the generated intensity can be driven by the incidence angle of the pump beam. A double circle construction, different from the conventional Ewald sphere, is adopted to explain the quasi phase matching process.
