Experts believe that a Chinese satellite fired down green laser beams that were spotted over Hawaii last month, amid growing tensions between the US and China after several foreign objects ...

Chinese satellite fires green laser beams over Hawaii as tensions escalate over spy balloon. Incident comes amid an escalation of tensions between China and the US – after a Chinese spy balloon ...

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 of ...

Macquarie University researchers have demonstrated a technique to dramatically narrow the linewidth of a laser beam by a ...

SpaceX's Starlink uses a dense network of low-orbit satellites to compensate for lower altitude and limited per-satellite capacity. The success of the Chinese satellite at a much higher orbit suggests ...

In terms of technology, laser links promise to transfer data between satellites and ground stations 10–40 times quicker than radio systems while utilizing beams that are roughly 1,000 times more ...

Seng Tiong Ho has made significant contributions to understanding how photonics are transforming communication in space exploration, improving satellite data transmission, and facilitating deep-space ...

How lasers work. A laser is a device for creating a narrow beam of directed energy. The first laser was developed in 1960, and since that time, there have been several types created that use ...

Engineers have developed the first room-temperature, eye-safe, photopumped PCSEL by embedding silicon dioxide into photonic crystal layer.

The US-owned satellite was capable of producing similar green laser beams; however, after a string of recent UFO activity was allegedly connected to China, the agency reversed its prior claim.

Astronomers have revealed that a Chinese satellite fired green laser beams over the state of Hawaii – at a time when tensions are boiling over between Beijing and Washington after several ...
