Abstract
6.3 Watts of single frequency output has been generated by single-pass frequency-doubling of a fiber-laser-pumped CW OPO. 40% efficient frequency doubling was demonstrated by focusing 15.8 Watts of 1560nm input into an 80mm length MgO:PPLN crystal. The single frequency 1560nm input was generated as the resonant signal wavelength in a CW OPO based on MgO:PPLN. The OPO was pumped by a 30 Watt Ytterbium-doped fiber laser operating at 1064nm, with a spectral bandwidth of ~0.6nm.
