New Laser Design Offers Multicolor Output of Tissue in Real Time

Facebook Twitter LinkedIn Email Comments
A cost-effective laser design that outputs multi-color lasing could improve information flow in optical fibers and allow multi-color medical imaging of diseased tissue in real time. The laser has been engineered to control the color and intensity of the light by varying the cavity architecture. Researchers at Northwestern University demonstrated multi-modal nanolasing using plasmonic superlattices — finite arrays of nanoparticles grouped into microscale arrays — to support multiple band-edge modes capable of multi-modal lasing at programmed emission wavelengths and with...Read full article
