These "Microlasers" Turn Infrared into Laser Light, and May Play a Role in Next-Gen Medical Tech

The biggest, brightest lasers make for good headlines, but this isn't a story about those. This is a story about lasers so tiny you need a microscope just to see them--lasers smaller than red blood cells. These tiny lasers could play an important role in next-generation medical care (among other technologies), and that makes them a big deal.
