Combining the telecom laser and the Erbium-doped fiber amplifier(EDFA)as well as the periodically-poled nonlinear crystals,we have realized~2.9W of single-frequency 780nm laser output and~84.2%of a maximum conversion efficiency based on bowtie-type four-mirror ring-cavity enhanced second-harmonic generation(SHG)of an EDFA-boosted 1560nm laser with a MgO:PPLN crystal in the cavity.
