An investigation was made of the kinetics of the luminescence due to /sup 4/I/sub 11//sub ///sub 2/..-->../sup 4/I/sub 15//sub ///sub 2/ and /sup 4/I/sub 13//sub ///sub 2/..-->../sup 4/I/sub 15//sub ///sub 2/ transitions in the Er/sup 3 +/ ion in yttrium erbium aluminum garnet crystals subjected to strong resonant excitation argon laser radiation (lambda = 4880 nm). The efficiency of the cooperative process resulting in nonlinear quenching of the luminescence from the /sup 4/I/sub 13//sub ///sub 2/ level and sensitization of the /sup 4/I/sub 11//sub ///sub 2/ level was estimated. The influence of this process on the kinetics of lasing as a result of the /sup 4/I/sub 11//sub ///sub 2/..-->../sup 4/I/sub 13//sub ///sub 2/ transition (lambda = 2.94 ..mu..) was analyzed.
