We tested four super bright flashlights that range from a laser-powered flashlight that shoots a beam over a .5 mile to a ...

Five years ago, two scientists conveyed considerable scientific interest in creating phonon lasers, which replace the oscillations of light waves with the vibrations of tiny solid particles.

The final setup uses the UV laser to pump a stilbene dye laser, which shoots a powerful pulse of 426 nanometer light into about 200 meters of fiber, and produces a gorgeous supercontinuum ...
