Abstract

The fluorescence and absorption variation of spectra of Er- and Yb/Er-doped phosphate and silicate glasses under CW Ti- sapphire laser were investigated. On pumping, the differential spectra demonstrated variations of spectral profiles. The reason of these variations is heating effect under high pump power. These variations were explained by a redistribution of the populations of the Stark sublevels of the ⁴I_15/2 ground and the ⁴I_13/2 excited manifolds. The heating effect under pumping was taken into account for measurement of quantum yield and determination of absolute values of up-conversion coefficients. Several techniques that reduce the heating effect on fluorescence, excited state absorption, and ground state absorption spectra due to pumping were proposed.
