Wladilen Stepanowitsch Letochow

from Wikipedia, the free encyclopedia

Wladilen Stepanowitsch Letochow ( Russian Владилен Степанович Летохов , English transcription Vladilen Letokhov ; born November 10, 1939 in Taischet , Irkutsk Oblast ; † March 21, 2009 ) was a Russian physicist who dealt with laser spectroscopy .

Letochow studied at the Moscow Institute of Physics and Technology from 1957 to 1963 and then at the Lebedev Institute , where he graduated from Nikolai Gennadijewitsch Basow in 1966. He stayed at the Lebedev Institute until 1970, where he received his doctorate in 1969 and completed his habilitation in 1970 (Russian doctorate). In 1970 he was visiting professor at the Massachusetts Institute of Technology . In the same year, at the invitation of Sergei Leonidowitsch Mandelstam, he went to the Institute for Spectroscopy of the Soviet Academy of Sciences , where he was head of the laser spectroscopy department. From 1971 to 1989 he was Deputy Director for Research. At the same time he was from 1972 professor at the Moscow Institute of Physics and Technology (1986 to 1998 he held the chair for quantum optics there). Since 2000 he has also been a professor at Lund University .

He was visiting professor at the University of Arizona (1996/97), the University of Paris-Nord (1993-1996), Regent Professor at the University of California, Berkeley (1993), visiting professor at the École normal supérieure (1998). In 1989 he was James Franck Lecturer at the Israel Academy of Sciences and in 1990 Emil Warburg Professor in Bayreuth.

The introduction of a gas cell at low pressure into the laser resonator with resonance absorption of the laser radiation (with generation of an inverse Lamb dip ) was introduced independently by Chebotayev in Novosibirsk, Letochow in Moscow and Skolnick at PerkinElmer in 1967/68. In 1969, Chebotayev and Letochov proposed the method of saturation-absorption spectroscopy.

In 1971 he proposed and demonstrated resonance ionization spectroscopy (RIS). He also applied laser spectroscopy in chemistry (the foundation of photoselective multiphoton chemistry), nuclear physics and medicine and biology. He was also involved early on in the manipulation of atoms with laser light (first publications in 1968, 1973) and in laser cooling.

He published over 850 scientific papers and 14 monographs. Letochow had 60 doctoral students and 12 post-doctoral students.

In 1978 he received the Lenin Prize with Weniamin Chebotayev . In 1995 he received an honorary doctorate from the University of Paris-Nord and in 2005 from the University of Lund . In 2002 he received the State Prize of the Russian Federation for Science and Technology and in 1998 the Quantum Electronics Prize of the European Physical Society. In 2000 he became an honorary citizen of Troitsk .

He was a Fellow of the Optical Society of America , an external member of the Max Planck Society , a member of the Leibniz Society and the European Academy of Arts and Sciences.
