Researchers at McGill University have developed a novel device that generates sound-like particles known as phonons at ...

Helium-neon lasers may be little more than glorified neon signs, but there’s just something about that glowing glass tube that makes the whole process of stimulated emission easier to understand. But ...

Ultrafast lasers tracked plasma formation and ionization in copper with picosecond precision. Results show rapid ion growth ...

Experiments have identified two main types of “breathing” behavior. When the laser operates above the minimum power needed to ...

Scientists may be on the cusp of launching a similar technological revolution — this time using light. In a significant advance toward that goal, the U.S. National Institute of Standards and ...

The ability of new blue-light semiconductor lasers to better perform precision cutting, patterning or welding of copper will make electrical and electronic component manufacturing cheaper and more ...

The winter months, when people spend significantly less time in the sun, are typically known as “laser season” by skin experts—if you’re considering a treatment, now is a great time. “We perform laser ...

Lasers may be the cure for whatever ails you in science fiction, but if America is looking for a real solution to the myriad problems posed by modern hypersonic weapons, lasers – or directed energy ...

The Iran war is testing the U.S. military's ability to combat Iran's drones in a cost-effective way. Emerging laser tech, designed to zap drones out of the sky, may help.
