ElectricOIL

The lasing state I* is produced by near-resonant energy transfer with metastable singlet oxygen O2(a1Δ) [denoted hereafter as O2(a)].

EOIL technology represents a unique class of hybrid electric gas high-energy laser with the potential to have inherently higher beam quality than solid state systems, while being more logistically friendly than current Chemical Oxygen Iodine Laser (COIL) systems.

The principal advantage of such an inherently high beam quality system is the trade of a relatively small fixed mass in electrical generation and heat exchanger hardware for the massive fluid supply and large tankage associated with COIL devices.

Ionin et al.[9] and Heaven [10] provide comprehensive topical reviews of discharge production of O2(a) and various EOIL studies.

The highest gain in an EOIL device reported to date is 0.30% / cm, and the highest output power reported is 538 W.[11] Over the past five years of research and development of the EOIL device, higher performance and efficiency have been consistently obtained by moving towards higher operating flow rates and pressures.
