Abstract :
The theory of second-harmonic generation (SHG) in birefringent crystals by a Gaussian beam with an elliptical cross section is developed in the assumption of no depletion of the fundamental beam. This study reveals that the doubling efficiency at optimum elliptical focusing is higher than at optimum circular focusing.
