摘要：

Frequency upconversion into green and red luminescence in erbium-ytterbium-codoped phosphate glass pumped with a 970 am diode laser is presented. The red upconversion emission results from a two-photon excitation process. The green emission results from a two- or three-photon excitation process with the two-photon process dominating at low pumping power. Based on measurement of the excitation and emission spectra, a model of the three-photon excitation process has been developed. This model provides a good basis for explaining the effect of the three-photon process on the saturation of 1.54 mum laser power of Er, Yb-codoped phosphate glass laser.
