Transparent P{sub 2}O{sub 5}-CaO-Na{sub 2}O glasses codoped with Er{sup 3+} and Yb{sup 3+} ions were fabricated by high-temperature melting technique. Strong near infrared and visible upconversion luminescence were observed under 975 nm laser diode excitation, and the luminescence processes were explained in details. For 1.54 {mu}m band, the calculated peak emission cross sections is 1.04x10{sup -20} cm{sup 2}, and it is better than that in germinate, tellurite, silicate, and other phosphate glasses. The near infrared upconversion emission around 828 nm contains two-photon and three-photon processes, and it is attributed to the transition {sup 4}S{sub 3/2}{yields}{sup 4}I{sub 13/2}, which enhances the population of the upper level for 1.54 {mu}m laser emission and reduces the energy loss due to upconversion. Efficient near infrared fluorescence indicates Er{sup 3+}/Yb{sup 3+} codoped phosphate glass is a promising laser and amplifier material.
