M.S. degree in physics from N. I. Lobachevsky State University of Nizhny Novgorod (2009). Current position: researcher at the Ultrafast process department at the IAP RAS, Nizhny Novgorod, Russia. Research interests: nonlinear optics and optical absorption measurement in ultrapure materials. Previous project: multistage frequency doublers of CW low-peak-power broadband laser radiation. An effective (30%) frequency doubling of radiation (at a wavelength of 1 μm) with a peak power of 300 W was demonstrated experimentally. Current project: developing a proposed method for measuring ultra-low absorptions. The project’s goal is to create a method for measuring impurity inclusions of metal ions at the ppt unit level in ultrapure quartz glasses.
