Paper Abstract

This is a review of tl Chemical Oxygen - Iodine Laser (COIL) technology, paying particular attention to historical perspectives in terms of highlighting the unique characteristics of COIL that have allowed it to develop into a high efficiency and a very forgiving system. Chemical pumping of lasing transitions has been around for a long time (HCI Lasers in 1965 and HF/DF Lasers in 1972), but most of the reaction energy ends up as heat in the lasing medium, generating the associated system engineering difficulties. COIL, on the other hand, has a very high efficiency in converting reaction energy to electronic excitation, and that fraction of the reaction energy which is released as heat does not end up in the laser cavity, but remains in the oxygen generator. This has tremendous engineering advantages for high efficiency systems.
