Lasers are getting smaller and more powerful — earlier this month, we saw the first-ever atomic scale laser, and now researchers are reporting the smallest telecommunications-frequency laser ever built. The laser is one-fifteenth the size of the light waves it can produce, and it works at room temperature.
Researchers at Harvard Medical School and Massachusetts General Hospital built a living laser partly to study interactions between electronic and biological systems, and partly out of sheer curiosity. The world’s first biological laser, made from a single living cell, could lead to better microscope imaging inside the body and even targeted light therapies, researchers say.
Producing color with ultra-precise lasers, these screens are set to stun

Those mad scientists at Mitsubishi have built the ultimate entertainment weapon—the laser TV! Lasers shooting out of a television screen isnt as scary as it may sound. But it does have one big benefit-color.
Lasers can be tuned to the exact wavelength of light you like—down to the nanometer. So TV makers can produce the ideal shades of red, green, and blue to produce the best colors possibly. Mitsubishi claims this allows them to reproduce about 80 percent of all the colors humans can see—versus about 40 percent for other TVs.
