Abstract

Conical pumping was used in a periodically poled ${\mathrm{KTiOPO}}_4$ optical parametric oscillator for singly resonant idler generation in a nearly diffraction-limited axial beam. A single signal–idler pair was generated over the whole tuning range by use of asymmetric reflectivity of the OPO mirrors. Pump depletion of 40% and total conversion efficiency of 27% were obtained. Additional OPO tuning capability was demonstrated by adjustment of the angle of the conical pump beam.
