General analysis of type I second-harmonic generation with elliptical Gaussian beams

, 1997
One can enhance second-harmonic generation in angle-tuned crystals by focusing the fundamental to an elliptical waist in the crystal. We present a general analysis for type I phase-matched uniaxial and biaxial crystals that will find particular ...
