摘要

The interaction of electromagnetic radiation with impurities in transparent solids is studied for the case when interactions between excitations become significant. It is shown that intense optical radiation leads to condensation of the excitations of impurities. The condensed excited state, consisting of excited impurites, is an energetically faviourable phase, which minimises the energy o f the system. Nevertheless, condensation, as a rule, causes mechanical stresses, in some cases followed by either redistribution of impurities or even breaches of solids.
