Ultrashort bursts of laser light are giving scientists a way to freeze one of chemistry’s most elusive moments, the instant ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

As summer comes to an end, dark spots, sun damage and emerging fine lines may be top of mind. Lasers are a high-tech, efficacious way to address these common skin concerns and many consumers are ...

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, a lot of ...

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

A team of scientists has found that the narrow beam of a laser, under specific conditions, can cast a shadow — a counterintuitive finding that could open the doors for new applications of optical ...

The Beth Sholom synagogue in Elkins Park, designed by Frank Lloyd Wright, is an unusual building even among the famed architect’s unique built works. Some have described it as a spaceship that landed ...

Researchers have created visible lasers of very pure colors from near-ultraviolet to near-infrared that fit on a fingertip. The colors of the lasers can be precisely tuned and extremely fast -- up to ...

The Friends of Arlington's Planetarium will be hosting two special evenings of laser shows at the David M. Brown Planetarium ...

For the experiment, a high-power green laser was directed through ruby cube and illuminated with a blue laser from the side. The green laser increases the optical absorption of the blue illuminating ...
