Physicist Optoelectronics Lazer physics Neolinear optics Physics Education: University of Cambridge BA 1962; University of Southampton Ph.D 1967 Career: Research student at the Department of Electronics, University of Southampton (1963); moved to the Department of Physics, University of Southampton (1984); Professor of Physics, University of Southampton (1988); Deputy Director of the Optoelectronics Research Centre (ORC) at the University of Southampton (1989); member of the International Council on Quantum Electronics (1994-1999) and the CLEO-Europe Steering Committee (1995-1997); Member of Governing Body, Winchester College (2001-2026); Emeritus Professor of Physics, School of Physics and Astronomy, University of Southampton. Awards/Medals: Max Born Prize 1993 EPS Applied Quantum Electronics Prize 2000 Charles Hard Townes Medal 2003 Made a considerable contribution to the understanding of laser physics and the control of laser devices. He applied a thorough, quantitative treatment to many important topics (for example, relaxation oscillations, resonators, mode selection, nonlinear optics, parametric oscillators and waveguide lasers) which were previously inadequately understood. His research on fibre lasers, in particular the Ytterbium-doped lasers, contributed greatly to a new generation of lasers which are compact, stable, highly efficient and capable of operating at very high powers. Had a pivotal role in the formation of the Optoelectronics Research Centre (ORC) at the University of Southampton.
