Alfred ("Alf") Rodney Adams FRS (born 1939[3][4]) is a British physicist who invented the strained-layer quantum-well laser.[5] Most modern homes will have several of these devices in their homes in all types of electronic equipment.[6][7][8]

He served as a Distinguished Professor of Physics at the University of Surrey, where he headed the Optoelectronic Materials and Devices Research Group. He is now retired and holds the position of emeritus professor. He was awarded the Duddell Medal and Prize in 1995, and elected as a Fellow of the Royal Society in 1996. In 2014 he was awarded the Rank Prize in Optoelectronics for his pioneering work on strained-layer laser structures.
