The spectroscopic and laser properties of Er:GGAG active medium, in temperature range from 80 K to 300 K, are presented in this work. The sample of Er:GGAG (20 at. % of Er3+) crystal had face-polished plan-parallel faces without anti-reflection coatings (thickness 3.6 mm). During all experiments the Er:GGAG was attached to temperature controlled copper holder and it was placed in a vacuum chamber. The transmission and emission spectra together with the fluorescence decay time were measured depending on temperature.
