Daniel J. Bradley

Daniel Joseph Bradley (born January 18, 1928 in Derry , † February 7, 2010 in Sandymound, Dublin ) was an Irish physicist who dealt with laser physics .

Bradley graduated from St Mary's College in Belfast in 1947 and graduated in 1947. While teaching, he graduated from the University of London with mathematics in 1953. He then taught mathematics at a school in London and studied physics in evening classes at Birkbeck College, University of London with a bachelor's degree with top grades in 1957. He then began a doctorate at Royal Holloway College , where he received his doctorate in 1961 with a thesis on optical spectroscopy with Sam Tolansky (with the development of Fabry -Pérot interferometers for high resolution). He was then a lecturer at Imperial College and from 1964 a reader at Royal Holloway College. From 1966 he was a professor at Queen's University Belfast . Due to the political unrest in Northern Ireland, he returned to Imperial College in 1973 as a professor of laser physics. From 1976 to 1980 he headed the physics faculty there. From 1980 he was a professor at Trinity College Dublin . For health reasons (stroke) he retired in 1984.

In 1989 he received the Charles Hard Townes Award . He was a Fellow of the Royal Society (1976) and received its Royal Medal in 1983 . In 2001 he received the Cunningham Medal from the Royal Irish Academy. He received honorary doctorates from the University of Ulster (1983) and Queen's University Belfast (1986). Bradley was a fellow of the Optical Society of America (1975) and the Institute of Physics (1959), whose Thomas Young Medal he received in 1975. In 1969 he became a member of the Royal Irish Academy .

He was a pioneer in laser research in the UK, where he was one of the founders of the Laser Center at the Rutherford Appleton Laboratory and had about 60 PhD students. In the 1960s and early 1970s, he was a pioneer in dye lasers and ultrashort laser pulses, and his group in Belfast attracted international attention at the time. At that time he also founded an electro-photonics company to market a picosecond streak camera . At Imperical College he later investigated nonlinear optical phenomena with excimer lasers and in Dublin semiconductor lasers. He has produced over 200 scientific publications.

He was married and had four sons and a daughter.
