Some weapons, such as [[Sontaran laser]]s, were called "lasers" despite travelling slower than light.

Lasers | === Uses of lasers === | ||
Lasers were frequently used in weaponry such as laser rays, beams, or guns. ([[TV]]: ''[[The Power of the Daleks (TV story)|The Power of the Daleks]]'' et al.) | |||
Lasers could also be used for a defensive purpose to guard vaults or other secure locations. If the laser beams were interrupted by a person, they would trigger an [[alarm]]. This method of defense could be defeated by changing the refractive index of the air, or by using a [[prismatic beam]]. ([[TV]]: ''[[City of Death (TV story)|City of Death]]'') | |||
Outside of weaponry or defense, lasers were also employed for peaceful purposes: | |||
* In [[surgery]], lasers were found in [[laser scalpel]]s ([[TV]]: ''[[Mindwarp (TV story)|Mindwarp]]'') and [[laser saw]]s. ([[TV]]:'' [[Children of Earth: Day One (TV story)|Children of Earth: Day One]]'') | |||
* They were also used for scientific purposes in material analysis, although the [[Third Doctor]] derided them as "primitive". ([[TV]]: ''[[Spearhead from Space (TV story)|Spearhead from Space]]'') | |||
* [[Hologram|Holograms]] were created using lasers to project light. ([[TV]]: ''[[The Talons of Weng-Chiang (TV story)|The Talons of Weng-Chiang]]'') | |||
* [[Laser scope|Laser scopes]] were used by the [[Dalek|Daleks]] on [[Skaro]] as surveillance devices. ([[TV]]: ''[[The Daleks (TV story)|The Daleks]]'') | |||
* [[Animal|Animals]] and their habitats could be converted into [[Magnetic energy|magnetic]] signals and held within laser crystals using a [[Continuous Event Transmuter]]. ([[TV]]: ''[[Nightmare of Eden (TV story)|Nightmare of Eden]]'') | |||
* A laser cutter could be used to cut circuits or other objects. ([[TV]]: ''[[Earthshock (TV story)|Earthshock]]'') Similarly, lasers could be used to bore into the crust of a planet. ([[TV]]: ''[[The Runaway Bride (TV story)|The Runaway Bride]]'') | |||
* The [[Tenth Doctor]] claimed to have owned a [[laser spanner]], ([[TV]]: ''[[Smith and Jones (TV story)|Smith and Jones]]'') which had a [[torch]]. ([[PROSE]]: ''[[The Mystery of the Haunted Cottage (short story)|The Mystery of the Haunted Cottage]]'') | |||
* Laser signals could be used to transmit information and to synchronise communications. ([[TV]]: ''[[Resolution (TV story)|Resolution]]'') | |||
