A high-repetition-rate Ti:sapphire-pumped optical parametric oscillator based on the new nonlinear optical crystal CsTiOAsO(4) is described. The operation of this optical parametric oscillator is characterized for a 90 degrees -cut crystal by use of a type II interaction. Tuning from 1.46 to 1.74 microm is demonstrated, and there is the potential for tuning from 0.9 to 5 microm 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.
