In the experiment, a high-power green laser passed through a ruby cube, illuminated from the side by a blue laser. The green laser increased the ruby’s absorption of the blue light, creating a darker ...
Researchers at the University of Maryland (UMD) have demonstrated a continuously operating optical fiber made of thin air. The most common optical fibers are strands of glass that tightly confine ...
Schematic of the optical experiment: Excitation near-infrared laser (red bottom one) - excites the nanodisk fabricated from the 3R-molybdenum disulfide flake, standing on a glass substrate. The ...
