Abstract
We report a new type of optical parametric oscillator cavity, i.e., a compound cavity with a grazing-incidence prism. The optical parametric oscillator is based on a β-BaB2O4 crystal and is pumped by the third harmonic of a Nd:YAG laser. Compared with the grazing-incidence-prism optical parametric oscillator (narrow-band cavity), the compound cavity has the same linewidth, whereas its threshold is only half as high and its external efficiency is an order of magnitude greater.
