The methods of influence of radiations are considered on solids with the purpose of their brightening. Most perspective is a method of influence a laser radiation, resulting in a phase transition in a matter. It is shown that using powerful lasers with a high output-input ratio and certain his office hours, terms are created for a phase transition in a solid at affecting him a laser radiation. Thus an irradiation can be made under any corner and on any frequency.
