Crystal creates a supercontinuum breakthrough
Researchers have generated a wide range of colors from a single laser after discovering a new process for achieving so-called "supercontinuum generation."
Supercontinuum generation is when intense laser light of one color travels within a material, like glass, and broadens into a spectrum of colors.
The effect lets scientists produce light at colors tailored to particular applications in sectors like bioimaging, optical communications and fundamental studies of materials.
Until now, there were two ways to create a supercontinuum. A special optical fiber, around 10% of the width of a human hair, could be used to concentrate light to a very high intensity, over lengths of a few meters.
