My first thought was to modulate a generic 650nm laser diode at a comparatively high frequency and make it a pulse-modulated laser transmitter. Also, employ a suitable laser receiver (capable of ...

The demonstration system consists of a flight laser transceiver, a ground laser transmitter and a ground laser receiver. The downlink transmitter has been installed on the Psyche spacecraft, which ...

The deep-space optical communication link could revolutionize how scientists communicate with spacecraft as they explore the ...

The United States’ Defense Advanced Research Projects Agency (DARPA) recently achieved a new record in transmitting energy over distance. In tests performed in New Mexico, the Persistent Optical ...

Ericsson’s engineers installed the Ericsson Streetmacro 6701 base station and PowerLight’s laser light receiver station onto a 22-foot-tall pole in a parking lot, about 400 feet from the ...

Now, researchers have created a system that, with a silent amplifier and record-sensitive receiver, ... a conventional laser transmitter with one wave can now be used to implement the amplifier.
