Ali Javan (Persian: علی جوان, romanized: Ali Javān); December 26, 1926 – September 12, 2016) was an Iranian American physicist and inventor. He was the first to propose the concept of the gas laser in 1959 at the Bell Telephone Laboratories .
The gas laser was the first continuous-light laser and the first laser to operate on the principle of converting electrical energy to a laser light output. The first gas laser, the Helium–neon laser (HeNe), was co-invented by Iranian engineer and scientist Ali Javan and American physicist William R. Bennett, Jr., in 1960. It produced a ...
Ali Javan: Invented the gas laser in 1960. Arno Allan Penzias: Discovered background radiation, with Robert W. Wilson, originating from the Big Bang and won the Nobel Prize in 1978 for the discovery. Amos E. Joel Jr.
He and Ali Javan co-invented the first gas laser (the helium-neon laser) at Bell Laboratories in Murray Hill, New Jersey. He discovered the argon ion laser, was first to observe spectral hole burning effects in gas lasers, and created a theory of hole burning effects on laser oscillation.
The basic LWI concept was first predicted by Ali Javan in 1956. [5] [6] The first demonstration of LWI was carried out by Marlan Scully in an experiment in rubidium and sodium at Texas A&M University, and then at NIST in Boulder. [7]
Michael S. Feld received his Ph.D. from the Massachusetts Institute of Technology under the supervision of laser pioneer Ali Javan. He remained at MIT throughout his career, where he was a faculty member from 1968 to 1976. He was the director of the George R. Harrison Spectroscopy Laboratory at MIT.
