Samofocousirovca of light in a theory was foreseen G.A. Asparyanom in 1962. First experimentally samofocousirovca was observed in a liquid Pilipetscim N.F. and Roustamovim A.R. in 1964 and intensively explored in sclah and transparent dielectrics. That is up to semiconductors, pione researches of the odnopouchcovogo samovliyaniya are begun by us at the end of sixtieth years (1965-1969 r.r.).

Samodifractsiya of light on dynamic holograms in semiconductors (Si) at odnofotonnom excitation of not nerivnovagnih free transmitters (NVN) first there was Verdmanom in 1969 the Use of twophotonic absorption NVN for the record of dynamic holograms in semiconductors first it is realized in our work in 1973 (Borsch, Brodin, Ovchar, Odoulov, Soscin).

In communication with wide development of researches of co-operation of intensive laser radiation with solids, in Institute of physics in 1965 was created department of nonlinear optics.

The academician of NAN of Ukraine heads a department from the day of his establishment and for today's time, laureate of the Leninist bonus, the State bonus of USSR, twice laureate of the State bonus of Ukraine, laureate of bonus of NAN of Ukraine the name C.D. Sinelnicova, the Honoured worker of science and techniques of Ukraine, doctor of fiz.-мат. sciences the professor M.S.Brodin.
