Characterization of a Ring Optical Parametric Oscillator
We have studied a singly-resonant KTP ring OPO pumped by nanosecond pulses from a frequency-doubled NdYAG laser. We present measurements of the temporal and spatial intensity profiles of the incident pump beam and OPO output beams, including the depleted pump, as well as the output energy as a function of pump laser energy. These measurements have been carried out for both injection-seeded and unseeded operation of the OPO The results of these measurements have been compared to the output of a computer model.
