Abstract
In media with spatial dispersion of properties the energy of an absorbed light quantum is shown to localize on small (〈v〉 = 10 −22 + 10 −21 cm −3 ) space scales. Energy transfer from electron subsystem to ion lattice is performed in two steps: on the first step high frequency local phonons are generated in a microregion, limited by the structural correlation radius, while on the second step they are transmitted to long wave propagating oscillations. Basing on this idea some physical effects in glasses (photodarkening, photoinduced anisotropy, photoluminescence) are considered.
