History of Science and Engineering Annotation << Back MARK EFREMOVICH ZHABOTINSKY IS ONE OF THE PIONEERS OF TECHNOLOGIES FOR CREATING QUANTUM FREQUENCY STANDARDS AND FIBER-OPTIC COMMUNICATION LINES IN THE USSR V.V. Kudryavtsev The life and scientifi c work of Mark Efremovich Zhabotinsky (1917–2002), a talented radio physicist, organizer and popularizer of science, public figure, and teacher are told. The scientific team led by him stood at the origins of the creation and implementation of quantum frequency standards, new laser materials, fiber-optic communication lines. The article uses archival materials that have not previously been introduced into scientific circulation. These materials provide an objective consideration and evaluation of the scientific contribution of M.E. Zhabotinsky in theoretical and applied radiophysics, as well as his activities in organizing scientific research. Keywords: radiophysics, history of Russian radiophysics, theory of nonlinear oscillations, electron paramagnetic resonance (EPR), quantum frequency standards, laser materials, fiber-optic communication lines (FOCL), Institute of Radio Engineering and Electronics of the USSR Academy of Sciences.
