A triangle of three spacecraft shooting laser beams at each other in space sounds like something from a science fiction movie. However, the European Space Agency revealed this will become a reality by ...

Cold, dark crater floors near the Moon’s south pole may hold one of space exploration’s most useful prizes: water ice. Yet ...

Dozens of times over the last decade NASA scientists have launched laser beams at a reflector the size of a paperback novel about 240,000 miles (385,000 kilometers) away from Earth. They announced ...

The inherent dispersion of laser beams limits their effectiveness in precision applications. Researchers at Chiba University, ...

A beam of electrons crossed just a few millimeters of plasma, then helped trigger an effect that usually belongs to massive ...

This case study focuses on an achromatic laser beam expander designed to magnify a 10mm input beam to a 50mm output beam, achieving 5X magnification at 1064nm and 5.1X at 532nm. Using a four-lens ...

Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long ...

A team of researchers created an ultra-thin chip to study infrared light, next thing they knew it was producing a green beam ...
