The luminescence kinetics of Yb{sup 3+} donors and Ho{sup 3+} acceptors is quantitatively studied in gallium-gadolinium garnet (GGG) crystals doped with Yb{sup 3+} and Ho{sup 3+} ions. It is shown that the sensitisation of transitions in Ho{sup 3+} ions occurs due to migration-accelerated (hopping) energy transfer. The microparameters of donor-donor energy transfer are determined at 300 and 77 K. The microparameters of donor-acceptor energy transfer are found at the same temperatures at the first stage of successive sensitisation (resulting in the population of the {sup 5}I{sub 6} state of Ho{sup 3+} ions) and at the second stage of successive sensitisation of the {sup 5}S{sub 2}, {sup 5}F{sub 4{yields}}{sup 5}I{sub 8} transition in Ho{sup 3+} ions. At the second stage of sensitisation, the values of the microparameter of reverse energy transfer are also determined. The possibility of obtaining lasing at sensitised transitions in Ho{sup 3+} ions in Yb{sup 3+}:Ho{sup 3+}:GGG crystals pumped into the absorption band of Yb{sup 3+} ions is discussed.
