Laser Cannon
these versatile weapons were essentially powerful blaster cannons that were used most often on starships. They could be mounted almost anywhere, provided that they could be powered separately from the ship's main power. There were many different sizes and configurations of laser cannons, from small, single cannons to the quad-laser cannons. They usually employed quad-helix prismatic crystals to generate a laser beam, which was focused through a polarized alloy. The color and size of the beam could be modified, allowing a ship to sometimes fire "invisible" lasers as part of a surprise attack. The physics of these invisible shots, however, were not detectable by most sensors, and could not be easily targetted.
