JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]An ultra-efficient on-chip supercontinuum laser developed by researchers at the University of Twente is poised to enable applications ranging from portable medical imaging devices to chemical sensing and lidar. The researchers’ design enabled control over the dispersion of light in the laser system by alternately widening and narrowing the beam of light. Lasers normally emit light that is coherent, meaning that the waves they emit are identical in frequency and waveform. The light’s coherent nature makes it possible to send a narrow beam over extreme distances with very low...Read full articleRelated content from Photonics MediaArticlesRaman Instrument Advances Study of Greener Fuels for AerospaceThere is much interest in developing aerospace engines that run on renewable, hydrogen (H2-rich) fuels.
