Yellow whispering-gallery-mode lasing from amorphous fluoride microspheres
Abhishek Sureshkumar, Jonathan Demaimay, Georges Perin +7
Compact, low-noise coherent light sources in the visible remain challenging due to limited gain platforms and inefficient pumping. We report a new route to visible microlasing base…
