C. Kumar N. Patel

Chandra Kumar N. Patel ( born July 2, 1938 in Baramuti ) is an Indian electrical engineer and physicist who deals with laser physics and a pioneer in the development of gas lasers was.

Patel studied at the University of Pune ( Bachelor's degree in Electrical Engineering in Telecommunications 1958) and at Stanford University, where he received his master's degree in 1959 and 1961 received his doctorate in electrical engineering at Dean Watson ( microwave electronics). From 1961 he was at Bell Laboratories, where he developed the carbon dioxide laser and other gas lasers. From 1967 he was head of the Infrared Physics and Electronic Research Department, from 1970, the Electronic Research Department and from 1976 to 1980 the Physical Sciences Laboratory. 1985 to 1993 he was also on the Board of Trustees of the parent company ATT. 1993, he joined Bell Laboratories, where he was Executive Director of Research Materials Science Engineering and Academic Affairs Division was most recently, the University of California, Los Angeles, as vice chancellor for research. Since 2000 he has been a professor of physics.

In addition to the development of the carbon dioxide laser in 1964 ( the first continuous laser with high power, which found numerous applications ), he made ​​important contributions to molecular spectroscopy, nonlinear optics, application of lasers in surgery, in the military and in the detection of pollution ( in the early 1970s with Raman lasers ). He also developed early tunable laser, first with the help of the Zeeman effect in gas lasers, which were, however, practically only limited use, then stimulated Raman scattering in a semiconductor in a magnetic field, which Patel and Earl D. Shaw in 1969 the first tunable laser developed in the infrared range (spin flip Raman laser, SFR laser), the Patel and colleagues then anwandten in the investigation of substances of very low concentration in the atmosphere.

In 1998 he received the Frederic Ives Medal, 1996, the National Medal of Science and the 1988 George E. Pake Prize of the American Physical Society, which he was president in 1995. In 1988 he was made an honorary doctor of the New Jersey Institute of Technology. He received the Adolph Lomb Medal of the Optical Society of America, the Zworykin Award from the National Association of Engineers, the Ballentine Medal of the Franklin Institute, the Lamme Medal of the IEEE in 1989 and the IEEE Medal of Honor He is a member of the National Academy of Sciences, the American Academy of Arts and Sciences and the National Academy of Engineering. He is a foreign member of the Indian National Science Academy and the Third World Academy of Sciences.
