IN MEMORY OF GENNADY KRUGLIK
Source: "Veda" (Minsk) No. 51 dated 12/20/2010
On December 21, 2009, Gennady Sergeevich Kruglik, Doctor of Physical and Mathematical Sciences, professor, well-known scientist and worker of higher education, passed away.
G. Kruglik was born in 1937 in the town of The bridle of the Minsk region in the family of a serviceman. He lost his parents early: his father died at the front in 1942, and his mother died in 1946. He grew up and was brought up by his grandmother in the village of Zhitkovo, Borisov district. In 1954, he graduated from high school with a gold medal and entered the Faculty of Physics and Mathematics of the Belarusian State University, which he also graduated with honors.
Even in his student years, G. Kruglik began to engage in scientific work and after graduating from the university he was recommended for postgraduate study at the Institute of Physics of the Academy of Sciences of the BSSR, where he worked until 1977. Here he defended his candidate's and doctoral dissertations, became a prominent specialist in the field of laser optics and theoretical physics.
In 1977, G. Kruglik was invited to work at the BPI. Here he successfully performed the duties of the head of the department of applied optics, worked as the dean of the Faculty of Engineering and Physics and vice-rector for academic affairs. On his initiative, the department of electronic and laser technology was created at this university, where scientific research in the field of laser physics was actively carried out. In 1987, at the BPI, the Intersectoral Institute for Advanced Studies and Retraining of Personnel was established (now IPKiPK BNTU in new areas of development of engineering, technology and economics), and the department of electronic and laser technology in full force entered into its structure. G. Kruglik was appointed director of the institute and worked in this position for more than 20 years.
Along with the skillful selection and placement of personnel, the scientist paid much attention to improving the forms and methods of organizing the educational process and scientific work. Under his leadership, a program, educational and educational-thematic plans for advanced training of engineering and technical workers of design, technological and research organizations of the republic in the direction of "Laser equipment and technologies" were developed. At the same time, he carried out the scientific management of the research laboratory "Laser Crystals".
The experience of G. Kruglik and his knowledge of a wide variety of issues of managerial activity have largely contributed to the successful development of the Institute throughout the entire period of its activity. Here, his best qualities as a team leader were manifested: competence, goodwill and respect for people, adherence to principles.
The theoretical work of the scientist on quantum optics and the quantum-static theory of ring lasers (lasers with a ring cavity) made a significant contribution to laser physics and received wide recognition in the scientific world. In his first major cycle of research, which ended with the defense of his Ph.D. thesis, he established a number of important regularities in the manifestation of the collective motion of atoms in the processes of absorption, emission and scattering of electromagnetic radiation. In the mid-1960s, G. Kruglik became actively involved in research in laser physics. At the same time, he concentrated his main attention on the development of the quantum-statistical approach in the theory of ring lasers as promising devices for the creation of laser gyroscopes. He carried out these studies in close contact with specialists from the NPO Zavod Arsenal (Kyiv), Central Research Institute "Electropribor" (Leningrad), Moscow Institute of Electromechanics and Automation, Research Institute of Applied Mechanics and Research Institute "Polus" (Moscow), which solved practical problems of creating such gyroscopes. As a result, high-precision laser gyroscopes capable of measuring very low rotational speeds were created with his participation. Unfortunately, the period of perestroika and the collapse of the USSR made it difficult to further develop these works. Despite this, the scientific cooperation of G. Kruglik with colleagues from St. Petersburg and Moscow continued until the last days of his life. Currently, laser gyroscopes are being produced in Russia, and we are sure that the works of the Belarusian scientist contributed to this in no small measure. solving practical problems of creating such gyroscopes.

G. Kruglik developed his own scientific direction, created an effective scientific school, prepared 9 candidates of science, 2 of whom became doctors of science. I would like to believe that the students and colleagues of Gennady Sergeevich will adequately continue the direction of research and development he created.
Everyone who was lucky enough to work with Gennady Sergeevich highly appreciated him not only as a scientist and teacher, but also as a person of high moral principles and great diligence.
