Professor Alf Adams FRS
Emeritus Professor of Quantum Physics
Biography
Professor Alf Adams FRS is a well-known British physicist who invented the strained-layer quantum-well laser, considered to be one of the top ten greatest UK scientific breakthroughs of all time. It powers the internet, CDs, DVDs, supermarket checkouts and billions of other devices.
About the lecture
Alf Adams briefly explained how lasers work and why the introduction of strain into semiconductors crystals enhances their ability to produce light. He presented examples and demonstrated why they are now such key components in modern technology.
The Lecture was hosted by Surrey's own Professor Jim Al-Khalili, well known for his television and radio documentaries and for his role in the public understanding of science -- as well as being a quantum physicist himself.
