Abstract: The absorption spectra and fluorescence spectra of a novel Er:Yb:phosphate glass were measured, and some emission parameters including the intensity parameters, integrated cross-section, emission cross-section, spontaneous emission probability were calculated by J-O theory. Green and red upconversion luminescence were obtained when excited with 966 nm LD, the mechanism of upconversion were analyzed in detail. Laser around 1.54 micrometers were obtained with the glass, the power is 5.2 mW.
