Abstract

We report a femtosecond optical parametric oscillator based on a periodically poled ${\mathrm{KTiOPO}}_4$ crystal for which quasi-phase matching is achieved with a $24-\mathit{\mu }\mathrm{m}$ poling period. The singly resonant parametric oscillator, synchronously pumped by a Ti:sapphire laser at a wavelength of 758 nm, generates a signal at 1200 nm and an idler at 2060 nm. The maximum signal power conversion efficiency of the device is 22% with a pump depletion of 69%. We tune the signal wavelength over a 200-nm band by changing the cavity length. In addition, pump wavelength tuning provides output tunability in the 1000–1235-nm range.
