LeGrand Van Uitert

from Wikipedia, the free encyclopedia

LeGrand Gerard Van Uitert , called Larry, (born May 6, 1922 in Salt Lake City , Utah , † 1999 ) was an American chemist who developed the Nd: YAG laser with Joseph E. Geusic in 1964 .

Van Uitert graduated from George Washington University with a bachelor's degree in 1949 and from Pennsylvania State University with a master's degree in chemistry in 1951 and a doctorate in 1952. He was a chemist at Bell Laboratories .

After Leo F. Johnson and K. Nassau had developed the first neodymium crystal laser at Bell Labs in 1961, Van Uitert, together with Ralph R. Soden and Scotch Plains, achieved the first continuous wave operation ( cw ) with a solid-state laser that included Rare earth was doped. In 1964 Van Uitert and Geusic (as well as Richard G. Smith, HM Marcos, Bob Thomas, Leo Johnson) at Bell Labs developed the first working Nd: YAG laser.

Van Uitert received the patent for the neodymium-YAG laser with Geusic in 1966. With Geusic he received the RW Wood Prize in 1993 and the IEEE's Quantum Electronics Award in 1992 . In 1975 he received the Howard N. Potts Medal and in 1976 the IRI Achievement Award . In 1981 he was awarded the American Physical Society's James C. McGroddy Prize for New Materials for the discovery and development of a number of materials of fundamental importance in magnetic and optical technology, including microwave ferrites, yarns for magnetic bubble storage elements and lasers, orthovanadate phosphorus, Molybdates and niabates for electro-optical elements and borosilicate glasses for optical waveguides . In 1978 he received the Creative Invention Award from the American Chemical Society and in 1971 the WRG Baker Award from the IEEE.

He was a member of the American Chemical Society and the National Academy of Engineering .
