pulse rifle

A raygun is a science-fiction directed-energy weapon that releases energy, usually with destructive effect. They have various alternate names: ray gun, death ray, beam gun, blaster, laser gun, laser pistol, phaser, zap gun, etc. In most stories, when activated, a raygun emits a ray, typically visible, usually lethal if it hits a human target, often destructive if it hits mechanical objects, with properties and other effects unspecified or varying.
Real-world analogues are directed-energy weapons or electrolasers: electroshock weapons which send current along an electrically conductive laser-induced plasma channel.
