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). Lasers could also be used for a defensive purpose, such as when the Doctor, Donna and Jenny came across a grid of heat rays in one of the tunnels underneath Messaline.
