Aleksandr Mikhaylovich Prokhorov , (born July 11, 1916, Atherton, Queensland, Australia—died January 8, 2002, Moscow , Russia), Soviet physicist who, with Nikolay G. Basov and Charles H. Townes , won the Nobel Prize for Physics in 1964 for fundamental research in quantum electronics that led to the development of the maser and laser .

Prokhorov’s father was involved in revolutionary activities that eventually forced the family to leave Russia . In 1911 they settled in Australia , where Prokhorov was born. Following the overthrow of the tsar (1917), the family returned to Russia in 1923. In 1951 Prokhorov received a doctorate from Leningrad State University and later joined the P.N. Lebedev Physical Institute, Moscow, as a senior associate. In 1952 he and Basov jointly suggested the maser principle of amplifying and emitting parallel electromagnetic waves that are all in phase and all of the same wavelength. By the time they published their suggestion in 1954, Townes had built the first working maser.

In 1954 Prokhorov became head of the institute’s Oscillation Laboratory and later professor at Moscow M.V. Lomonosov State University. He wrote a number of fundamental works on the construction of infrared and visible-light lasers and on nonlinear optics. From 1969 to 1978 he served as editor in chief of the Bolshaya Sovetskaya Entsiklopediya ( Great Soviet Encyclopedia ). Prokhorov received the Lenin Prize (1959) and two Orders of Lenin as well as various medals.
