The first high-powered, randomly polarized laser beam with a 'Q-switched' laser.


An international team of scientists has produced the first high-powered, randomly polarized laser beam with a "Q switch" laser, which typically emits pulses of light so brief that they're measured in nanoseconds. Lasers are a critical part of modern technology—they're used in everything from our automobiles to medical equipment to the satellites orbiting Earth. Now, researchers are broadening the potential applications of even smaller and more powerful lasers.

"The experimental evidence provided in this study advances this research field toward the realization of actively controllable integrated micro lasers," wrote Taichi Goto, second author of the paper and an assistant professor in the department of electrical and electronic information engineering at the Toyohashi University of Technology in Japan.
