Quantum torch

Quantum torch

Lasers are everywhere, and David Coutts helps us explore some of the quantum ideas behind these amazing light sources.

David is a professor at Macquarie University and has worked with numerous exciting lasers - including some that produce light in Aussie green-and-gold colours. It's fascinating to realise just how widely lasers are used, even if they're often a bit behind the scenes. They can also be quite exciting, with beams able to drill a hole in your eye or even blast rust off metal! David explains how lasers work and various ways they can be built.
