Abstract: We report a continuous-wave (CW) KTA (KTiOAsO4)-OPO (optical parametric oscillator) with a compact linear cavity utilizing an LD pumped mixed crystal Nd:Lu0.5Y0.5VO4 laser as the pump source for the first time. A singly resonant oscillator with low signal light loss was designed to reduce the OPO's threshold. Maximum output powers of 630 mW at 3475 nm and 190 mW at 1536 nm were obtained at a pump power of 13.2 W. A total conversion efficiency of 6.2% was achieved with respect to the incident diode pump power. The performance of this work demonstrates that a CW KTA-OPO derived by an LD pumped Nd3+ doped solid laser can also produce efficient mid-infrared light.
