He developed highly efficient lasers which are currently commercially available in Russia. For his work on the physics of lasers and optical systems, MA Kazarian together with team members were awarded the State Prize of the USSR in the field of science and technology for 1980. M.A.Kazarian together with A.M.Prokhorov, Yu.V. Gulyaev and Yu.A.Trutnev have developed many aspects of modern laser physics and its applications. In 2003 he was elected a full member of the A.M.Prokhorov Academy of Engineering Sciences and in 2008 a Foreign Member of the National Academy of Sciences of the Republic of Armenia. Mishik Kazaryan is a supervisor of many international projects of ISTC and CRDF. Currently, he is the scientific secretary of the Scientific Council on Luminescence, a member of program and organizing committees, chairman of the sections at many national and international conferences. Misik Kazaryan lectures on physics of lasers and their applications in many research centers and universities in Russia and many other countries. Under the leadership of Prof. Kazaryan a number of specialists, working in Russia and in the CIS countries and abroad, was prepared. Prof. Kazaryan is a member of the editorial board of international scientific journals Lasers in Engineering, Alternative Energy and Ecology, a member of the Council of the Euro-Asian Physical Society, a member of the "National Foundation of Science and Advanced Technologies" in Armenia.
