Optimum conditions for elliptical focusing are derived for singly resonant optical parametric oscillators with hemispherical resonator in dependence on double refraction. By elliptical focusing it is possible to focus more tightly in the non‐walk‐off plane. In a LiNbO 3 oscillator pumped with 1,06 μm radiation the threshold pump power can be lowered about a factor 6 by elliptical focusing in comparison with circular focusing.
