The spectral and kinetic characteristics of Er3+ ions in heavily doped BaY1.8Lu0.2F8 mixed crystals have been studied. Absorption and luminescence spectra were recorded for BaY1.8Lu0.2F8 crystals with Er3+ ion concentrations of 20.0 and 30.0 at.%. The kinetic dependences of luminescence decay in the infrared range have also been studied. A model of the level populations of Er3+ ions is constructed on the basis of a three-level scheme for pumping the 4I11/2 state at a wavelength of 970 nm without taking into account up-conversion processes. The gain of BaY1.8Lu0.2F8 crystals with Er3+ ion concentrations of 20.0 and 30.0 at.% is estimated at different pump powers.
