Photonics experts at Heriot-Watt University are hailing a breakthrough in laser research.

They have come up with a new and relatively inexpensive way of creating a laser supercontinuum.

They hope it could eventually have applications in bio-imaging and optical communications.

What is a Supercontinuum?

Generation of a supercontinuum happens when intense laser light of a single colour travels through a material and then broadens into a spectrum of colours.

This might at first seem a bit like splitting white light into a rainbow of colours via a prism.

However, in a supercontinuum, each colour retains the tight and precise qualities of laser light when it is separated.
