A high-repetition-rate Ti:sapphire-pumped optical parametric oscillator based on the new nonlinear optical crystal CsTiOAsO4 is described. The operation of this optical parametric oscillator is characterized for a 90°-cut crystal by use of a type II interaction. Tuning from 1.46 to 1.74 µm is demonstrated, and there is the potential for tuning from 0.9 to 5 µm with angle tuning. Powers of 100 mW in the signal and the idler branches are obtained. Pulse widths as short as 64 fs are generated with and without prisms in the cavity.
