Gas Phase Lasers: Proven High Quality Power

CUA has decades of experience with efficient high energy laser (HEL) technologies. Personnel at CUA can perform experiments, modeling, and systems analyses for many HEL technologies.

CUA invented and demonstrated an exciting variant of the chemical oxygen-iodine laser (COIL) system that draws its power from electrical rather than chemical energy (ElectricOIL or EOIL), thereby improving its safety and mass-scaling characteristics. Additionally, CUA co-invented a variant of the diode pumped alkali laser (DPAL) called the exciplex pumped alkali laser (XPAL).

COIL and ElectricOIL are high power chemical lasers that are unique because of their strong coupling to most materials and their ability to transmit through the atmosphere as well as through common fiber optics. CUA personnel also have decades of experience with older hydrogen-fluoride (HF) and deuterium-fluoride (DF) laser systems.

Applications for gas phase high energy lasers are primarily tactical and missile defense for the military. The chemical laser technologies remain as the highest performing laser systems in terms of power, beam quality at high power, and demonstrated ability to destroy missiles at a distance.
