Abstract

We report on recent studies aimed at improving the chemical efficiency of the supersonic chemical oxygen-iodine laser (COIL). Efficiencies around 30% for the supersonic COIL have been the state-of-the-art in the last decade. By carefully studying and optimizing the operation of the chemical generator, the mixing of reagents in different nozzles and the optical extraction efficiency, we achieved a new record (40%) for the chemical efficiency of the supersonic COIL and approached the theoretical limit for this efficiency. The effects of the partial pressure of O₂ and the residence time of the flow in the generator, as well as the heating of the nozzle, are discussed and shown to be crucial in attaining this high efficiency.
