A spectrum laser represented a certain kind of laser that saw deployment among different military organizations operating within the Unknown Regions. The starships belonging to the Chiss Ascendancy were known to employ spectrum lasers, a practice mirrored by the warships of the Paataatus, the vessels of the Garwian Unity, and also the Nikardun Destiny. It was noted that at longer ranges, spectrum lasers proved to be less effective when targeting ships protected by electrostatic barriers.
Spectrum lasers were uniquely identified by their ability to rapidly adjust their energy frequencies, optimizing them for maximum absorption by the specific target material. It was possible to utilize spectrum lasers to create a phenomenon referred to as a "light show."
