Supersonic cw chemical oxygen-iodine laser

Summary form only given. Supersonic continuous wave (cw) chemical oxygen-iodine lasers (COIL) have been studied for many years. By using the rotating disk O/sub 2/ generator and using supersonic gas flow instead of subsonic gas flow in the laser cavity, the laser output power has been improved. We got 5-kW laser output power with Cl flow rate at 0.3 moles/second.
