LABORATORY of macrokinetics of non-equilibrium processes

 

 

 

The contribution of the laboratory to investigation of laser-matter interactions is recognized worldwide. Physical and chemical modifications of materials induced by laser light at both m m and nm scale is the mainstream of the research at the lab. Theoretical and experimental activity includes both fundamental aspects of matter self-organization in a laser beam and a wide spectrum of practical applications of the research. The laboratory has close relationships with Universite Paris-7 (France), Space Vacuum Epitaxy Center at Huston, Texas (USA), and P.N. Lebedev Physical Institute of RAS. The laboratory won numerous national and international grants (RFBR, Soros grants, and INTAS)
