An Indian's homemade laser device, dubbed a "mosquito missile system," has gone viral for instantly zapping pests.

A computational paradigm that can accurately simulate interactions between powerful laser beams and quantum fluctuations in a ...

A massive green and blue laser beam was spotted in the San Francisco sky earlier this week, and despite plenty of speculation online, no one seemed to know much about its purpose or origin ...

Blue lasers, lasers that emit a light beam with a wavelength between 400 nm and 500 nm, are key components of various technologies, ranging from high-resolution displays to printers, medical ...

"It's made up of six total Nu-Salt Laser Space Cannons - two blue, two red, and two green that focus together making one bright purple laser beam," he said. Ant that's the key. Lasers, not LED ...

The green light increases the absorption of the blue beam, creating a darker region that casts the shadow. The researchers measured a maximum contrast of around 22 percent, roughly the equivalent ...

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.

Turin, Italy-based laser module manufacturer Convergent Photonics is developing new sources for high-power industrial and mid-power medical laser applications thanks to the introduction of a new ...

Conspiracy theorists are pushing for people to paint their roofs blue over the belief that it will protect them from fire-starting lasers. The belief finds its roots in comments from Rep. Majorie ...

Specifically, the green laser drives some of the crystal’s electrons into an excited state, and when they decay, they enter a state where they absorb blue light that would otherwise pass through.
