Scientific activity

Bagayev discovered new qualitative features of the absorption of laser radiation by a gas at low pressure. Bagaev's scientific work encompasses optical spectroscopy, laser physics, and quantum electronics. In the field of optical spectroscopy, he has conducted notable experiments on the quantum Doppler Effect. His contributions to laser physics have significantly advanced the discipline, while his expertise in quantum electronics has led to further recognized developments in that domain. The physicist was a member of the editorial boards of Russian and international journals: ''Quantum Electronics'', ''Laser Physics'', ''Applied Physics B: Lasers and Optics'', ''Optical Review'', ''Opto-Electronics Letters'').
