Alexander Mikhailovich Sergeev (b. 02.08.1955, v. Buturlino, Nizhny Novgorod Region, Russia) - physicist. Foreign Member of the National Academy of Sciences of Belarus (2017), Academician of the Russian Academy of Sciences (2016; Corresponding Member since 2003), Doctor of Physico-Mathematical Sciences (2000), Professor.
Scientific research in the field of plasma physics, femtosecond optics, the theory of nonlinear wave phenomena, plasma physics and biophotonics. He carried out the fundamental work on the theory of nonlinear interaction of ultra-short-duration optical fields with matter, predicted and studied new physical phenomena in femtosecond optics and physics of super-strong fields, created unique sources of ultrashort-pulse laser radiation and demonstrated their new applications. Under his leadership, a modern center for femtosecond optics, including the most powerful in Russia and one of the most powerful petawatt laser complexes in the world based on parametric light amplification, was created at the Institute of Applied Physics of the Russian Academy of Sciences. New ways of using femtosecond radiation for processing materials and medicine were developed. The author of the project to create the world's most powerful subexawatt laser XCELS, which is included by the Government of the Russian Federation among the 6 projects of the megasiens class for implementation in the current decade. He heads an interdepartmental team of physicists and physicians who have developed physical principles and have implemented in clinical conditions methods of optical tomography of biological tissues, including optical coherent tomography, optical diffusion tomography, diffusion fluorescence tomography, ultramicroscopy.
Author of more than 350 scientific papers.
State Prize of the Russian Federation (1999) for the work “Optical coherent tomography. Physical fundamentals and applications". Russian Government Prize (2012) for the development and implementation of petawatt laser power complexes based on parametric light amplification. Gruber Award in Cosmology (2016) for the work on the detection of gravitational waves in the framework of the international project LIGO.
Awarded with the Order of Honor (2006). Officer of the Order of Academic Palms (2018, France).
