From Wikipedia, the free encyclopedia
Nikolai Delaunay, Jr. (aka Delone, Nikolai Borisovich; 22 May 1926 – 11 September 2008) was a Soviet physicist born in Leningrad, USSR (now Saint Petersburg, Russia).[1]
Delaunay was born in Leningrad on 22 May 1926. He was the son of Boris Delaunay, a mathematician known for creating the Delaunay triangulation.[1] He graduated from the Moscow Engineering Physics Institute in 1951, and obtained his PhD at the Lebedev Physical Institute in the late 1950s.[1]
Delaunay is recognized for the first observations of multiphoton ionization, in 1965.[1][2] Delaunay, along with Maxim Ammosov and Vladimir P. Krainov, developed the ADK formula, relating tunneling ionization in laser fields.[1] He was also a lecturer at the Moscow Institute of Physics and Technology.[1] After the dissolution of the Soviet Union, he travelled abroad and worked on international collaborations on multiphoton physics.[1]
His son was Vadim Delaunay, a poet and dissident, who participated in the 1968 Red Square demonstration of protest against military suppression of the Prague Spring.
