Continuous wave single frequency intracavity singly resonant optical parametric

We present a 1.5-\mum continuous-wave (CW) single-frequency intracavity singly resonant optical parametric oscillator (SRO) based on periodically poled lithium niobate (PPLN). The SRO is placed inside the ring cavity of a single-frequency 1.06-\mum Nd:YVO4 laser pumped by a laser diode. The device d
