Widening the range of colours step by step supercontinuum

Description

A wide range of colours, a so-called ‘supercontinuum’, made from a laser bundle that is narrow by itself, is very attractive. In an autonomously driving car, for example, the object recognition using a LIDAR system is possible thanks to a supercontinuum. Most techniques for creating a supercontinuum, however, encounter problems. Simply enlarging the laser power often doesn’t solve these. Scientists of the University of Twente now present an approach that avoids losing the peak power of the laser. The colour range therefore is expanded step by step. They publish about it in ‘Laser & Photonics Reviews’.
