A 2-watt laser, no brighter than a nightlight, has just delivered data at 1 gigabit per second from a satellite 36,000 kilometers above Earth five times faster than Starlink, and with a fraction ...

In a significant scientific achievement, NASA has successfully transmitted a laser signal over an astounding distance of 290 million miles - the greatest distance between Mars and Earth.

Science Truck Receives Laser Signal from Space in First-of-Its-Kind Demonstration The test is part of ongoing efforts to increase space-to-Earth communication speeds by 1,000-fold.

SIGNAL Magazine published an article in 1975 featuring laser communications, or lasercomm, devices. Demonstrations of optical communications technologies occurred in the mid-’90s.

Xiaomi is showing off its Modular Optical System concept at MWC 2025, but the most interesting part of it is its LaserLink technology.

And the system employs a commercial off-the-shelf laser, the same laser used in automobile manufacturing to cut out hoods. The weapon can be placed on an adjustable tripod for static ground ...

An experiment aboard NASA’s Psyche mission achieved “first light” by sending and receiving its first deep-space laser communications from far beyond the moon.

Recent innovation at the University of Southampton’s (U.K.) Optoelectronics Research Centre have developed an alternative approach for optical signal analysis when using sensors to monitor composite ...

Business News Leuko raises $5M for optical white blood cell monitor 27 Sep 2022 MIT spin-out is developing a microscope platform for label-free imaging of human blood cells as they flow through ...

The surface-emitting laser developed in this study incorporates nanoscale semiconductor structures called quantum dots as light-emitting materials.

A doughnut-shaped laser was used to create a 45-metre-long optical fibre out of air, and a pulse of light was then sent through it. The technology could eventually be used to detect radioactive ...
