The FC10 (10-mm aperture) and FC20 (20-mm aperture) laser fiber collimators provide a centered beam with a clean Gaussian profile of less than 1/10-wave wavefront ...

Tesla has been working on a technology consisting of laser beams installed on vehicles, and other products, to automatically clean debris off the windshield of its cars. No, I am not kidding. If you ...

In the last few decades, only temporal modes have been considered for mode-locked fiber lasers using single-mode fibers. Mode-locked single-mode fiber lasers offer advantages due to their high-gain ...

Right now, NASA estimates, more than 500,000 pieces of debris are clogging Earth's orbit, slinging around the planet at 17,500 mph. The danger to spacecraft and satellites is obvious, even if you ...

The NASA Artemis missions aim to send astronauts to the moon by 2024. But to succeed, they’ll need to solve big problems caused by some tiny particles: dust. Horányi and colleagues have discovered a ...

A team of engineers is working on a real life “tractor beam,” a staple device of spacefaring sci-fi that can push and pull objects at a distance without making contact. Tantalizingly, their early ...
