Powerful laser guide star system at the Paranal Observatory. The actual laser guide star is the small spot above the apparent end of the laser beam. A laser guide star is an artificial star image created for use in astronomical adaptive optics systems, which are employed in large telescopes in order to correct atmospheric distortion of light (called astronomical seeing).
Starfire Optical Range (SOR - Pronounced as an initialism) is a United States Air Force research laboratory on the Kirtland Air Force Base in Albuquerque, New Mexico.Its primary duty, according to the official website, is to "develop and demonstrate optical wavefront control technologies."
Furthermore, the Automated Planet Finder at Lick Observatory is searching for optical signals coming from laser transmissions. The massive data rates from the radio telescopes (24 GB/s at Green Bank) necessitated the construction of dedicated hardware at the telescopes to perform the bulk of the analysis. [60]
The radio telescopes are sensitive enough to detect "Earth-leakage" levels of radio transmission from stars within 5 parsecs, [4] and can detect a transmitter of the same power as a common aircraft radar from the 1,000 nearest stars. [12] The Green Bank Telescope began operations in January 2016, and the Parkes Telescope from October 2016. [4]
A long-range laser rangefinder is capable of measuring distance up to 20 km; mounted on a tripod with an angular mount. The resulting system also provides azimuth and elevation measurements. A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object.
A telescope in the Very Large Telescope system producing four orange laser guide stars. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word laser originated as an acronym for light amplification by stimulated emission of radiation.

A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the ...
