Born in Swinemunde, Germany (1946). M.S. degree in radiophysics (1970), N.I. Lobachevsky Gorky State University. 1970-1976-Radiophysical Research Institute, Gorky (Nizhny Novgorod), junior researcher. 1976-transferred to work as a researcher at the Institute of Applied Physics, USSR Academy of Sciences. Performed a series of experimental and theoretical works on nonlinear laser optics of ns and ps pulses. The main achievements relate to stimulated molecular & Raman scattering on vibrations and rotations of molecules in a real atmosphere. For the first time, these types of scattering were observed at pressures equal or close to atmospheric. The values of their threshold characteristics were obtained experimentally and theoretically and the features of the polarization characteristics were studied. The laser pulses self-compression effect, which had no theoretical explanation at that time, was observed for the first time during the study of stimulated molecular backscattering at atmospheric conditions. 2002-2004-Passat Ltd. (Canada, USA), senior researcher. Worked on the problem of obtaining high-power 10 ns laser pulses at λ=6.45 μm using nonlinear optics methods for creating a low-cost device for performing brain operations without large burn areas around the incisions (funded by the National Institute of Health). 2005-present-IAP RAS, senior researcher. Current interest: study of optical absorption in ultrapure quartz materials to improve the technology of their production.
