Abstract

The absorption and fluorescence spectra of Er-doped phosphate and silicate laser glasses were investigated in temperature range of 20 - 300 degree(s)C. The heating resulted in 5 - 10% decrease of oscillator strengths of spectral bands. On the base of temperature variations of spectral profiles we proposed an energy level model, which allowed to explain the thermal variation of spectrum of Er-laser at 1.54 micrometers .
