When atoms collide, their exact structure—for example, the number of electrons they have or even the quantum spin of their ...

The effect occurs because the green laser increases the optical absorption of the blue illuminating laser beam, creating a matching region in the illuminating light with lower optical intensity.

Lasers are known for the monochromatic nature of their light, so much so that you might never have thought there could be such a thing as a white laser. But in the weird world of physics ...

It’s a rare person who can pick up a cheap laser pointer ... laser precisely. The effects can be interesting; we had no idea comms-grade fiber could leak as much light through the cladding ...

"If it's possible in nature, we should be able to utilize similar effects in artificial ... absorb energy from the light and then release that extra energy as laser light. With the new grant ...

while laser hair removal involves damaging hair using laser light. Both methods have the potential for mild side effects like redness and swelling. When treated by a board-certified medical ...

A new study shows that when combined with lasers, atomic clocks can help us catch the most mysterious matter in the universe.
