The design and performance of a continuously operated singly resonant synchronously pumped potassium titanyl phosphate optical parametric oscillator is described. With an all-solid-state pump source providing 2-ps pulses at 523 nm, we found that the oscillation threshold pump intensity was ~60 MW cm<sup>-2</sup>, in good agreement with design calculations. The output of the optical parametric oscillator provided transform-limited pulses of 1-2-ps duration at a 125-MHz repetition rate, continuously tunable over the range of 938-1184 nm, with tens of milliwatts of average power.
