A '''laser''' was an artificial beam of light that travels in a single direction. Many lasers were harmless and used in some games ([[SJA]]: ''[[Warriors of Kudlak]]''), but other lasers were used as deadly weapons. During their campaign to recruit warriors, the Uvodni utilised harmless laser weapons in their interactive laser-tag game Combat 3000. However, on board their ship, the Kudlak warriors carried deadly blaster rifles that fired a yellow laser burst.

=== 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]]'', etc.)
 
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]]s were created using lasers to project light. ([[TV]]: ''[[The Talons of Weng-Chiang (TV story)|The Talons of Weng-Chiang]]'')
* [[Laser scope]]s were used by the [[Dalek]]s on [[Skaro]] as surveillance devices. ([[TV]]: ''[[The Daleks (TV story)|The Daleks]]'')
* [[Animal]]s 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]]'')
 
== Examples of laser weapon use ==
During his [[43]] [[AD]] scheme, [[the War Chief (The Legions of Death)|the War Chief]] put his hypnotised prisoners to work constructing [[laser weapon]]s of his own design for themselves, including unusually compact [[Laser Pistol]]s. ([[GAME]]: {{cite source|The Legions of Death (game)}})
 
The [[Third Doctor]] used a [[laser stick]]. ([[COMIC]]: ''[[Backtime (comic story)|Backtime]]'') The [[Eleventh Doctor]]'s [[The Doctor's sonic screwdriver|sonic screwdriver]] was able to fire a defensive laser, capable of stunning a [[Cybermat]]. ([[TV]]: ''[[Closing Time (TV story)|Closing Time]]'') When the [[Twelfth Doctor]] left one of these screwdrivers in the possession of a young [[Davros]], the [[Kaled]] increased the output of the laser into a true weapon, one capable of burning flesh. ([[PROSE]]: ''[[The Last of the Dals (short story)|The Last of the Dals]]'')
 
The [[Cyberman (Pete's World)|Cybermen]] were armed with a wrist-mounted laser blaster that fired a red blast. ([[TV]]: ''[[The Pandorica Opens (TV story)|The Pandorica Opens]]'')
 
The [[Dalek]]s used gunsticks which fired laser rays which could be modified into hand-held Tommy rifles. ([[TV]]: ''[[Evolution of the Daleks (TV story)|Evolution of the Daleks]]'')


Some weapons, such as [[Sontaran laser]]s, were called "lasers" despite travelling slower than light. ([[DW]]: ''[[The Sontaran Strategem]]''). Weapons from older Doctor Who serials tended to fire the instantaneous beams while most weapons in newer episodes fire slower-moving 'bolts'. Ironically, the older weapons were actually more realistic.  Lasers can also be used for defensive purposes such as when the Doctor, Donna and Jenny came across a grid of heat rays in one of the tunnels underneath Messaline.
[[Graske]] on the planet [[Griffoth]] were armed with tiny laser pistols which fired purple blasts to combat intruders. ([[GAME]]: {{cs|Attack of the Graske (video game)}})


==Examples of laser weapons being used==
The [[Torchwood (Pete's World)|parallel Torchwood]] developed laser weapons, which destroyed [[Cybusman|Cybermen]] and could blast through a Dalek's shield. ([[TV]]: ''[[Doomsday (TV story)|Doomsday]]'') These weapons were later upgraded, to the point that they could destroy Daleks in one shot. ([[TV]]: ''[[The Stolen Earth (TV story)|The Stolen Earth]]'')
*The [[Cybus Cybermen|Cybermen]] were armed with a wrist-mounted laser blaster that fired a red blast. ([[DW]]: ''[[Rise of the Cybermen]]'', ''[[The Age of Steel]]'')
*The [[Daleks]] used gunsticks which fired laser rays which could be modified into hand-held Tommy rifles. ([[DW]]: ''[[Evolution of the Daleks]]'')
*The parallel Torchwood  developed laser weapons, which destroyed [[Cybus Cybermen|Cybermen]] and could blast through a Dalek's shield. ([[DW]]: ''[[Doomsday]]'')
*Captain [[Jack Harkness]] used components from a pair of androids to build a high-powered energy weapon out of a defabricator. ([[DW]]: ''[[Bad Wolf (TV story)|Bad Wolf]]'')
*The [[Sontaran]]s utilised laser rifles during their [[The Poison Sky|Invasion]] attempt. ([[DW]]: ''[[The Poison Sky]]'')
*The [[Judoon]] carried hand-held blaster pistols which fired a red disintegrator beam. ([[DW]]: ''[[Smith and Jones]]'')
*The [[Toclafane]] had laser blasters built in to their casings. ([[DW]]: ''[[The Sound of Drums]]'')
*On the planet Griffoth, the [[Graske]] were armed with tiny laser pistols to combat intruders.
*[[Sontaran]] batons fired a laser that could cripple their victims. ([[DW]]: ''[[The Poison Sky]]'')
*[[Chantho]] used a laser pistol to shoot the Master. ([[DW]]: ''[[Utopia (TV story)|Utopia]]'')
*Suki used a laser pistol to shoot the [[Jagrafess]]. ([[DW]]: ''[[The Long Game]]'')
*[[Novice Hame]] carried a laser gun for protection when searching for [[Tenth Doctor|the Doctor]]. ([[DW]]: ''[[Gridlock]]'')
