Abstract
A 3.5 W fiber-based laser source at 772 nm is demonstrated by using quasiph ase-matched second-harmonic generation of a 40 dBm seeded ytterbium-erbium fiber amplifier in PPKTP. A 40% conversion efficiency is achieved across th e entire output power range of the EDFA. No optical damage has been observe d in the PPKTP over long-term high-power exposure.
