A high-repetition-rate Ti:sapphire laser is used to synchronously pump a type-II angle-tuned CsTiOAsO{sub 4} (CTA) optical parametric oscillator. When pumped at 809 nm, the optical parametric oscillator is tunable from 1.007 to 1.180 {mu}m in the signal branch and from 2.590 to 4.120 {mu}m in the idler branch. Powers as high as 235 mW are obtained in the signal branch. Pulse widths as short as 56 fs are generated at 1.115 {mu}m. CTA is shown to have a unique combination of low walk-off and low dispersion that contributes to its high gain and conversion efficiency. {copyright} 1995 Optical Society of America
