In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

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 ...

Researchers have built a new platform that produces ultrashort UV-C laser pulses and detects them at room temperature using ...

Ultraviolet-B (UV-B) semiconductor lasers are highly sought for medical, biotechnology, and precision manufacturing applications; however, previous UV-B laser diodes were limited to pulsed operation ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

These lavender-scented cloths come in a pack of 12 and work to quickly remove dirt and grime while minimizing floor streaks left behind. Compared to name brands like Swiffer, which retail for $9.94 at ...

A new ultraviolet laser source pushes maskless lithography closer to mainstream use in advanced semiconductor packaging by ...
