Fotonkanon

Fotonkanon, or photon cannon, is a fictional directed-energy weapon that uses photons to generate a concentrated beam or pulse for offensive or defensive purposes. The term appears across science-fiction media, where photon cannons are typically depicted as high-powered, beam-based devices or defensive towers.

In the StarCraft series, the Photon Cannon is a Protoss defensive structure placed at bases to deter attackers. It is a stationary turret that automatically targets enemy units within its range and fires a continuous photon beam. Its operation depends on an energy source provided by Protoss pylons, and it is designed to protect key locations by engaging both air and ground units in many iterations of the game.

Beyond StarCraft, photon cannons appear in various works as stationary defense installations or portable devices, generally presented as high-energy beam weapons with specialized deployment requirements and cooldown periods. The concept underscores the broader science-fiction appeal of energy-based weapon systems rather than conventional ballistic arms.

In real-world discussions of technology, the term photon cannon remains fictional, though it echoes ongoing exploration of directed-energy weapons and laser-like systems. The idea continues to influence portrayals of futuristic warfare and secure installations in games, films, and literature.
