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 ...

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 ...

"Laser light casting a shadow was previously thought impossible since light usually passes through other light without interacting," study co-author Raphael Abrahao, a physicist at Brookhaven National ...

Scientists get peacock feathers to emit laser light after adding dye and green pulses, revealing surprising biophotonic ...

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 ...

Thin layers of organic molecules can be fabricated over large areas at low cost, and their electrical and optical properties can be chemically tuned with ease. These characteristics make organic ...
