The laser is fed with gaseous chlorine, molecular iodine, and an aqueous mixture of hydrogen peroxide and potassium hydroxide.
The excited iodine atoms 2P1/2 then undergoes stimulated emission and lases at 1.315 μm in the optical resonator region of the laser.
The low pressure and fast flow make removal of heat from the lasing medium easy, in comparison with high-power solid-state lasers.
[3] All gas-phase iodine laser (AGIL) is a similar construction using all-gas reagents, more suitable for aerospace applications.
The ElectricOIL, or EOIL, offers the same iodine lasing species in an alternate gas-electric hybrid variant.
