Ion I. Agârbiceanu (6 January 1907 – 9 March 1971) was a Romanian physicist born in Bucium, Alba County in Transylvania. He was the son of the writer and Greek-Catholic priest Ion Agârbiceanu and his wife Maria.[1]
After completing his secondary education at the George Barițiu High School in Cluj,[2] Agârbiceanu studied from 1925 to 1929 at the Electrotechnic Institute of Bucharest.[3] He then pursued his studies at the University of Paris, where he obtained in 1934 his Ph.D. in Physics under the direction of Aimé Cotton;[3] his thesis, Recherche sur le spectre de fluorescence et d'absorption des vapeurs de Iodine, was published in Annales de physique.[4] From 1951 to 1955 he was a professor in the Faculty of Mathematics and Physics of the University of Bucharest, after which he transferred to the Polytechnic Institute of Bucharest.[3]
He invented the gas laser in 1962, the first major improvement on laser technology, which was discovered by Theodore Maiman. Agârbiceanu's laser used a mixture of helium and neon to function. This laser was invented during Agârbiceanu's long tenure as head of Physics Lab 1 at the Polytechnic Institute of Bucharest, which lasted from 1955 to 1971.[1] He was elected a corresponding member of the Romanian Academy in 1963.[5]
Agârbiceanu died in Cluj on 9 March 1971, a scant few months after he stopped working for the Polytechnic Institute of Bucharest.[1][3]
