We report the first realization of a high-power, singlefrequency, green-pumped continuous-wave optical parametric oscillator (OPO) capable of providing rapid and continuous tuning across wide spectral range in the near-infrared at room temperature. By exploiting the nonlinear crystal of MgO:sPPLT in a fan-out grating design, pumped at 532 nm in the green, the OPO can be tuned continuously across 1097-2100 nm in the idler, with corresponding signal tuning over 712-1033 nm using simple mechanicaldoi:10.1364/ol.42.002635 pmid:28957303 fatcat:bitsmb7pvncxbef3tuom4ckvuy
