Popis:	Maximum gain of 23 dB at 780 nm and a broadband optical gain with full width at half maximum (FWHM) of 88 nm (761–849 nm) were obtained from the Tm 3+ /Nd 3+ codoped fiber upon pumping at 1550 nm. The enhancement of the upconversion emission stretching from 730 to 970 nm was observed in the Tm 3+ /Nd 3+ codoped fiber due to the energy transfer from Tm 3+ to Nd 3+ ions.
