Scientists have used a pair of lasers and a supersonic sheet of gas to accelerate electrons to high energies in less than a ...

Q. How do laser levels work? Laser levels project a fixed red or green beam of light from a diode to establish a level horizontal or vertical line. This line serves as a reference point for ...

Can light itself cast a shadow? It may sound like a philosophical riddle, but researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow.

An array of colors is available such as red, green ... Optics can be integrated into laser modules to ensure that the output is as clear as possible. Lasers are classes of devices that produce beams ...

and a simple lens to collimate the output beam. (Note that this is possible because the laser diode's output falls within the red spectrum.) Conversely, because laser diodes which output light in the ...

Copper’s optical absorption of blue light is almost 10 times higher than for red and infrared light ... on top of one another, and the laser beam is further defined by an etched channel through ...

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 ...
