Researchers used powerful XFELs to trigger strong inner-shell lasing, producing attosecond hard X-ray pulses. Filamentation ...

Once only a part of science fiction, lasers are now everyday objects used in research, health care and even just for fun. Previously available only in low-energy light, lasers are now available in ...

LASIK eye surgery costs a couple of thousand dollars, depending on what insurance may or may not pay for it. Find cost averages and financing options here.

Centrosymmetric crystals have always absorbed equal amounts of left- and right-handed circularly polarized light—until now ...

This new laser can change its light frequency at a rate of 20 quintillion times per second. That’s a 2 followed by 19 zeros. No other laser has done this before at this speed and accuracy.

Optical fibers with a hollow core, made of air instead of solid glass, are known as hollow-core optical fibers. In comparison ...

Night blindness is caused by vitamin A deficiency, congenital mutations, and other eye diseases. Learn about symptoms, causes ...

This mask emits 633 nm and 830 nm red light, as well. The 1,072 nm light is directed where signs of aging are especially noticeable: on the forehead, at crow’s-feet, and at the nasolabial folds.

Now, a team led by Professor Sascha Feldmann at EPFL’s Laboratory for Energy Materials has developed a high-sensitivity, ...

Harvard and PSI scientists have managed to freeze normally fleeting quantum states in time, creating a pathway to control them using pure electronic tricks and laser precision.

Narrowband performance Altogether, the laser demonstrated an outstanding performance on a single chip – producing a clean, single wavelength with very little noise. Most importantly, the light had a ...

With IO Interactive, the creators behind Hitman, revealing the first look at its James Bond game, 007 First Light, this week, it’s clear we are in for quite the treat.
