Apollonov V.V. is the leading specialist in the area of basic principles of creation and development of high power laser systems and high power laser radiation interaction with matter. He has made an outstanding input into creation and development of new branches of science - physical and technical fundamentals of high power laser optics and adaptive optics, investigation of physical processes in a high volume self-controlled volume discharges, creation of high power continuous wave, pulsed and high repetition rate pulse-periodic laser systems, high intensity laser radiation interaction with matter, high power laser application for an effective protection of valuable objects and water surface cleaning from oil films, medical applications for UV lasers. Recent results of his investigations related to the laser diode arrays phase-locking, mechanisms of shock waves merging for a rockets launch by high repetition rate pulse-periodic laser light, super long conductive channel based on the electrical breakdown in a dust plasma produced by mechanism of ablation, high repetition rate optical pulsating discharge applications, space debris elimination by laser, scalable mono-module disk laser and high power laser applications in the Arctic are under very intensive implementation in our country and abroad. He is the author of 1923 research publications (19 books, 546 presentations and 148 patents, 954 articles, inf. from Research Gate). Apollonov V.V. is a high profile scientist and well known around all over the world, for more than 49 years of his international scientific activity, he has participated and organized more than 60 international conferences, symposiums and workshops, prepared 32 candidates and doctors of physics and mathematics. For the last 5 years his scientific group has fulfilled more than 60 R and D contracts with customers from Japan, UK, Germany, France, China, Korea, Singapore and USA. He is the General Director of â€œEnergomashtechnikaâ€ Ltd. Apollonov V.V. is the member of European and American Physical Society, SPIE, AIAA, American Society for QE and the member of specialized scientific council of Russia. He is a full member of Russian Academy of Natural Science and Academy of Engineering Sciences, member of the Presidium RANS. He is the laureate of State Prize of USSR (1982) and of Russia (2001).
