Early life

Alexander Michael Prochoroff was born on 11 July 1916 at Russell Road,

Butchers Creek, situated about 30 km from Atherton), to Mikhail Ivanovich Prokhorov and Maria Ivanovna (née Mikhailova), Russian revolutionaries who had emigrated from Russia to escape repression by the tsarist regime. As a child he attended Butchers Creek State School.[2][3]

In 1923, after the October Revolution and the Russian Civil War, the family returned to Russia. In 1934, Prokhorov entered the Saint Petersburg State University to study physics. He was a member of the Komsomol from 1930 to 1944. Prokhorov graduated with honors in 1939 and moved to Moscow to work at the Lebedev Physical Institute, in the oscillations laboratory headed by academician N. D. Papaleksi. His research there was devoted to propagation of radio waves in the ionosphere. At the onset of World War II in the Soviet Union, in June 1941, he joined the Red Army. During World War II, Prokhorov fought in the infantry, was wounded twice in battles, and was awarded three medals, including the Medal For Courage in 1946.[4] He was demobilized in 1944 and returned to the Lebedev Institute where, in 1946, he defended his Ph.D. thesis on "Theory of Stabilization of Frequency of a Tube Oscillator in the Theory of a Small Parameter".[1][5][6]

Research

In 1947, Prokhorov started working on coherent radiation emitted by electrons orbiting in a cyclic

quantum electronics. The group focused on a special class of molecules which have three (non-degenerate) moments of inertia. The research was conducted both on experiment and theory. In 1954, Prokhorov became head of the laboratory. Together with Nikolay Basov he developed theoretical grounds for creation of a molecular oscillator and constructed such an oscillator based on ammonia. They also proposed a method for the production of population inversion using inhomogeneous electric and magnetic fields. Their results were first presented at a national conference in 1952, but not published until 1954–1955;[1][6]

In 1955, Prokhorov started his research in the field of

In 1959, Prokhorov became a professor at

German Academy of Sciences Leopoldina.[8] Between 1982 and 1998, Prokhorov served as acting director of the General Physics Institute of the Russian Academy of Sciences, and after 1998 as honorary director. After his death in 2002, the institute was renamed the A. M. Prokhorov General Physics Institute [Wikidata] of the Russian Academy of Sciences.[5][6] Prokhorov was a Member and one of the Honorary Presidents of the International Academy of Science, Munich and supported 1993 the foundation and development of the Russian Section of International Academy of Science, Moscow.[9][10]

In 1969, Prokhorov became a

Optical Society of America (OSA), in 2000[11] and became an Honorary OSA Member in 2001.[12] The same year, he was awarded the Demidov Prize.[13]

He died on 8 January 2002 at Moscow and was buried at Novodevichy Cemetery.

Both of Prokhorov's parents died during World War II. Prokhorov married geographer Galina Shelepina in 1941, and they had a son, Kiril, born in 1945. Following his father, Kiril Prokhorov became a physicist in the field of optics and is currently leading a laser-related laboratory at the A. M. Prokhorov General Physics Institute.[4][18]
