In this work, mode-mismatched thermal lens and spectroscopic measurements were performed using Er3+-, Nd3+-, and Pr3+-doped lead-indium-phosphate glasses to obtain the thermal diffusivity and conductivity, ds/dT, the thermal loading (nonradiative quantum efficiency), and eta. The experimental difficulties associated with obtaining eta for systems with several emitting levels, such as Er3+-doped materials were overcome. A discussion of the implications of the small eta values obtained for Er3+- and Pr3+-doped glass is presented.
