A laser is a directed-energy technology utilizing a beam of light in which all wavelengths are equal and all particles are in phase with one another. Due to this, the photon's motion is almost parallel, which allows the beam to travel over a great distance with very little increase of the beam's square area and the resulting loss of energy per area. Laser is an acronym for Light Amplification by the Stimulated Emission of Radiation. Lasers have a variety of uses in medicine, computers, mining and power generation, such as fusion reactors.
A laser beacon was part of the Starfleet equipment issued aboard the USS Enterprise. Lieutenant DeSalle used the laser beacon to attempt to signal the ship visually from the surface of Gothos. (TOS: "The Squire of Gothos")
Laser weapons also exist, such as the advanced laser pistols and laser cannons used by Starfleet in the 2250s, and the high-energy X-ray lasers mounted aboard Talarian warships. (TOS: "The Cage"; TNG: "Suddenly Human")
The Altec used laser weapons on their ships and once targeted them on the Enterprise-D in an attempt to acquire the Straleb Jewel of Thesia and Thadiun Okona. Picard noted that such lasers would not even penetrate their navigation shields. (TNG: "The Outrageous Okona")
