The integrated absorption cross section, the spontaneous emission probability, and the stimulated emission cross section of Yb 3+ were determined in silicate, phosphate, borate, germanate, aluminate, gallate, and ZBLAN host glasses. The compositional dependence of the stimulated emission cross section of the 2 F 5/2 → 2 F 7/2 transition is determined mainly by the integrated absorption cross section in the glasses. A peak stimulated emission cross section above 1 pm 2 , which is the highest value in glasses, was obtained in a gallate glass with a composition of 40K 2 O·20Ta 2 O 5 . 40Ga 2 O 3 . The factors affecting the integrated absorption cross section are discussed using the Judd‐Ofelt parameters of Er 3+ calculated in previous studies.
