Copper’s low absorption of red or infrared light also means that ... thin semiconductor films are deposited on top of one another, and the laser beam is further defined by an etched channel ...

Two-photon technology, which relies on overlapping light beams, can be used for three ... the written bits are illuminated with a red laser diode that induces fluorescence from the written bits ...

We hate to admit it, but laser cutter beam alignment is no easy task. To greatly assist in this endeavor, though, some folks tend to mix a red diode laser into the path of the beam. Others ...

[Martin] explains that there are basically two schools of thought: a head-mounted laser, or a beam combiner. In both cases, a small red diode laser (the kind used in laser pointers) is used to ...

Anyone familiar with optics labs is familiar with the extremes of light coherence: laser beams are highly coherent, producing clear interference patterns used for precise applications like atomic ...

When a Gaussian beam encounters a circular aperture, the fraction of the power passing through is equal to This rule applies to beams that are characterized as Gaussian in radial intensity pattern.

SUITA, Osaka Prefecture--Researchers here succeeded in zapping crop-damaging moths with laser beams, a development that has wide implications for parts of the world that suffer insect infestations.

Nasa has streamed an ultra high-definition video of a cat back to Earth from the depths of space. The 15-second clip of Taters the cat was sent via laser - and fittingly shows it chasing a laser beam.

Man blinds a police helicopter by shining a laser beam at it. The helicopter was searching for a missing person in Cheshire.

Understanding how to read a tape measure is crucial for any home or professional project. Tracking multiple measurements and keeping the equipment in top-performance shape can often be a challenge.
