The researchers are now able to further increase the amplitude of the scan angle multiplier by making additional changes inside their invention. They have started a company, called Pacific Optica, to ...

Low-power optical device achieves around 100 times amplification using just a couple of hundred milliwatts of input power ...

In the experiment, a high-power green laser passed through a ruby cube, illuminated from the side by a blue laser. The green laser increased the ruby’s absorption of the blue light, creating a darker ...

Physicists have forced light to behave like electrons trapped in a magnetic field, reproducing the quantum Hall effect with photons for the first time. The experiment, carried out on an optical fiber ...

WASHINGTON – Two small satellites launched last summer by the Defense Advanced Research Projects Agency successfully established an optical link on April 14 during a nearly 40-minute test, according ...

Engineers have developed an experimental strategy to control and observe the chemical reaction of a single nanocatalyst using an optical microscope -- Expected to contribute to catalyst design based ...
