Microtheoretical estimation of laser influence on superconductivity

The microtheoretical estimation of the superconductive gap behaviour in the electromagnetic field is given. The approach to the problem is based on the mechanism of the retarded interaction between electrons. Ii is shown that the light quanta mainly decrease the magnitude of the superconductive gap. Also, the possibility to increase the gap is discussed, but the result is obtained under conditions near the limit of the validity of the method used.
