Rodney Loudon’s work focuses on various aspects of theoretical solid state and laser physics, and particularly on light scattering. His 1964 paper on the Raman effect was one of the 100 most cited papers in all areas of physical science between 1960 and 1969. He has published more than 190 papers and 3 books, one of which (the three editions of The Quantum Theory of Light) has a very high international reputation and has been translated into Russian and Japanese.
His early work on excitons, phonons and magnons and his later treatments of non-classical effects in the statistical properties of light have attracted many citations. His most recent work on surface excitations and on optical amplification, attenuation and detection has also proved to be important.
Rodney has played a full role at the University of Essex as Professor, Chairman and Dean. He has also worked at BT, RRE, Bell Telephone Laboratories and RCA, and he has been a consultant to these organisations over several years, contributing to applied as well as fundamental research.
