title: Continuous-wave, pump-enhanced optical parametric oscillator based on periodically-poled RbTiOAsO4.
abstract: The operation of a continuous-wave optical parametric oscillator (OPO) based on periodically-poled RbTiOAsO4 (PPRTA) and using a pump-enhanced cavity configuration is described. The OPO was pumped by a single-frequency Nd:YVO4 laser and temperature tuning ranges of 1.525-1.583ìm and 3.245-3.520ìm were achieved at the signal and idler, respectively. The external threshold was 250mW and up to 87mW of idler was generated. Fine-tuning behavior of the OPO and material quality of the PPRTA were investigated. We believe this to be the first reported example of an externally-pumped cw OPO based on PPRTA.
