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 ...

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 ...

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 CoS packaged laser diodes offer a compact alternative to the familiar TO can. Several CoS lasers can be combined in one module to save space. For this, micro-optic lenses are mounted adjacent to ...

Crafted from stainless steel and copper, this laser pen emits a powerful blue laser beam at a wavelength of 400 and 50 nanometers, visible over super-long distances of 10000 millimeters and 20000 ...

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.

The green laser increases the crystal’s ability to absorb the blue laser beam. which creates a matching region in the blue beam that appears as a shadow. If you read the article, there’s more ...
