text: Basov graduated from Moscow Engineering Physics Institute (MEPhI) in 1950. He then held a professorship at MEPhI and also worked in the Lebedev Physical Institute (LPI), where he defended a dissertation for the Candidate of Sciences degree (equivalent to PhD) in 1953 and a dissertation for the Doctor of Sciences degree in 1956. Basov was the Director of the LPI in 1973–1988. He was elected as  corresponding member of the USSR Academy of Sciences (Russian Academy of Sciences since 1991) in 1962 and  Full Member of the Academy in 1966. In 1967, he was elected a Member of the Presidium of the Academy (1967—1990), and since 1990 he was the councillor of the Presidium of the USSR Academy of Sciences. In 1971 he was elected a Member of the German Academy of Sciences Leopoldina. He was Honorary President and Member of the International Academy of Science, Munich. He was the head of the laboratory of quantum radiophysics at the LPI until his death in 2001.
  In the early 1950s Basov and Prokhorov developed theoretical grounds for creation of a molecular oscillator and constructed such an oscillator based on ammonia. Later this oscillator became known as maser. They also proposed a method for the production of population inversion using inhomogeneous electric and magnetic fields. Their results were presented at a national conference in 1952 and published in 1954. Basov then proceeded to the development of laser, an analogous generator of coherent light. In 1955 he designed a three-level laser, and in 1959 suggested constructing a semiconductor laser, which he built with collaborators in 1963. Basov  with co-workers proposed Disk laser in 1966   and realized experimentally the thin disk active mirror semiconductor lasers.
  He developed with colleaguaes the first nonlinear theory of coherent addition of laser sets.
   N.G.Basov encouraged the researchers in nonlinear optics in Lebedev Institute who discovered the optical phase conjugation. 
  Together with Lebedev Institute researchers he realized the robust method of the phase-locking of laser arrays via  optical phase conjugation in Stimulated Brillouin scattering. 
  Basov's contributions to the development of the laser and maser, which won him the Nobel Prize in 1964, also led to new missile defense initiatives.
  He died on 1 July, 2001 at Moscow and was buried at Novodevichy Cemetery.
