Their system was also able to re-acquire tracking after the signal was lost due to cloud cover. On December 7, 2021 NASA launched the Laser Communications Relay Demonstration (LCRD), which aims to relay data between spacecraft in geosynchronous orbit and ground stations. LCRD is NASA's first two-way, end-to-end optical relay.
In 1962, MIT Lincoln Labs built an experimental OWC link using a light-emitting GaAs diode and was able to transmit TV signals over a distance of 30 miles. After the invention of the laser, OWC was envisioned to be the main deployment area for lasers and many trials were conducted using different types of lasers and modulation schemes. [6]

In 2008, the ESA used laser communication technology designed to transmit 1.8 Gbit/s across 40,000 km (25,000 mi), the distance of a LEO-GEO link. Such a terminal was successfully tested during an in-orbit verification using the German radar satellite TerraSAR-X and the American Near Field Infrared Experiment (NFire) satellite.
Since intensity noise typically is proportional to the intensity, the relative intensity noise is typically independent of laser power. Hence, when the signal to noise ratio (SNR) is limited by RIN, it does not depend on laser power. In contrast, when SNR is limited by shot noise, it improves with increasing laser power. RIN typically peaks at ...
The Zapper is an electronic light gun accessory launched within the Nintendo Entertainment System (NES) in North America on October 18, 1985. It is a cosmetic redesign by Nintendo of America's head designer Lance Barr, based on Gunpei Yokoi's Video Shooting Series light gun (光線銃シリーズガン), which had been released in Japan for the Famicom on February 18, 1984.
