We compare the relative merits of the new nonlinear materials CsLiB6O10 and β-BaB2O4 for use as gain media in a singly or doubly resonant pulsed optical parametric oscillator pumped by a Q-switched Nd:YAG laser with various parameters. Angle tuning or a wide range can be theoretically stimulated under type I and type II(1) critical phase matching for CsLiB6O10 crystal. The tunable range is 237–2775 nm; the range was extended to the ultraviolet wavelength by fifth-harmonic generation in CsLiB6O10. A comparison of the tunable ranges, resonant thresholds, and conversion efficiencies of CsLiB6O10 and β-BaB2O4 is obtained by computer simulation. We verify that CsLiB6O10 is an excellent ultraviolet crystal.
