Richard M. Osgood Jr.
Richard Magee Osgood Jr. (December 28, 1943 – October 20, 2023) was an American applied and pure physicist (condensed matter and chemical physics of surfaces, laser technology, nano-optics). He was Higgins Professor of Electrical Engineering and Applied Physics at Columbia University.
Richard Magee Osgood Jr. was born on December 28, 1943. He began his scientific career in 1966, after graduating from the U.S. Military Academy with a bachelor's degree in 1965. He obtained a master's degree in 1968 from the Ohio State University. In 1973 he graduated from the Massachusetts Institute of Technology Ph.D. in physics. From 1973 to 1981, he then was on the scientific staff of MIT Lincoln Laboratory. In 1981 he was appointed to the faculty of Columbia University and in 1988 he was made "Higgins Professor" at Columbia University. From 1984 to 1990, he served as Co-Director of the Columbia Radiation Laboratory and in 1986 was founder and until 1990 director of the Microelectronics Sciences Laboratories (MSL) at Columbia University.
In 1980 he served on the "Ad Hoc" U.S. Department of Energy Committee for laser isotope separation. From 1984 to 2001 he was an advisor to the Laser and Laser and Chemistry Divisions of Los Alamos Scientific Laboratory. From 1985 to 2002, he was on the advisory board of the Defense Advanced Research Project Agency (DARPA Defense Sciences Research Council). From 2000 to 2002 he served as associate director of the Brookhaven National Laboratory (Basic Energy Sciences Directorate) and in 2002 Acting Director of the Nanoscience Centre. During this period DOE agreed to build the Center for Functional Nanomaterials at Brookhaven and the Department of Materials Science was initiated. He was in the Basic Energy Sciences Advisory Board of the Department of Energy (DOE) in the mid-1980s.
Osgood was married to Alice (née Dyson) and had three children, Richard M. III, a physicist, Nathaniel D., a computer scientist, and Jennifer Smestad, an attorney. He also had six grandchildren. Richard M. Osgood Jr. died on October 20, 2023, at the age of 79.
His research falls into two broad areas: 1. Condensed matter and chemical physics studies of surfaces; 2. Optical physics and devices. Thus his research has included extensive studies in basic studies in optical-excited and -probed surface physics and chemistry, in the development of new infrared and UV lasers, optical physics, application of lasers for material processing.
His major research highlights are as follows.
He, along with William Eppers, developed the first high power CO laser (a quantum cascade gas laser), as well as other infrared lasers including the first high powered 16 um laser for isotope separation. In 1979 he developed with Daniel Ehrlich and Peter Moulton a UV solid-state laser, then the optically pumped solid-state laser with the shortest wavelength.
Osgood, along with Ali Javan, made the first direct observation of vibrational-vibrational energy transfer and exchange in hydrogen halides. Later he made the first direct observation (with Steven Brueck) of vibration energy flow in molecules in cryogenic liquids the studies. A notable results of this work was the observation of the extremely long (60s) lifetime of N2 in its cryogenic state.
