From Tardis Wiki, the free Doctor Who reference
An impulse laser was a handheld weapon used by Time Lords. It fired a red, flickering beam.
Hedin killed Talor with an impulse laser. He later used it to threaten Borusa. (TV: Arc of Infinity)
Braxiatel later claimed that they were not much good as a weapon unless the tip of the weapon was overloaded. (AUDIO: Disassembled)
