Abstract
We present a CW optical parametric oscillator (OPO) based on quasi-phase-matching. Pumped at 532 nm, the OPO provides coherent radiation from 800 nm to 900 nm and from 1300 nm to 1600 nm for signal and idler, respectively. Application for calibrating the spectral responsivity of Si and InGaAs photodiodes is demonstrated.
