The chemical oxygen-iodine laser (COIL) is one of the most promising and extensively studied chemical lasers. Nevertheless, the mechanisms governing its operation are not yet fully understood and efforts are underway to find better singlet oxygen chemical generators and improve oxygen/iodine mixing schemes. The latter efforts are briefly reviewed and recent results of parametric studies of an efficient supersonic COIL operating in our laboratory are presented. The laser is energized by a jet type generator, operating without primary buffer gas and applies simple nozzle geometry and mixing of iodine and oxygen at or after the critical cross section.
