Laser

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.

Some weapons, such as Sontaran lasers, were called "lasers" despite travelling slower than light. (DW: The Sontaran Strategem). Weapons from older Doctor Who serials tended to fire the instantanious 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.
