Abstract
A theoretical study is presented that enables the calculation of the optimal focusing parameters in a singly resonant optical parametric oscillator and difference-frequency generation with elliptical foci. The effect of diffraction, phase matching, beam walk-off, and resonator astigmatism are included in the model. The results show that an optimal focusing configuration is obtained with unequal confocal beam parameters and that an elliptical beam profile can substantially increase the conversion efficiency when beam walk-off is present in the crystal.
