What makes laser light so special?
When we look at a light source, we can immediately tell whether the source is a laser or not, but what are the main properties that a laser has that distinguish it from any other “normal” source of light.
Oscar Price and Adam Bekele have spent a week at the Photonics Group at Imperial College London working on some theoretical aspects to describe laser behaviour. In this episode, Adam and Oscar will tell us something about properties such as monochromaticity, directionality and coherence, that make of the laser a very special form of light.
