Reliable fine tuning of the all-fiber laser over 6.9 at 603 nm has been demonstrated using high strength fiber Bragg gratings.all-fiber devicesfiber Bragg gratings (FBGs)tunable lasersupconversionOPTICAL FIBERSFLUORIDE FIBERUP-CONVERSIONTEMPERATUREDEGRADATIONBLUEUP-CONVERSION[OFD]text::journal::journal article::research article
