Abstract: Experiments were carried out on a verti-chemical oxygen-iodine laser (COIL), which was designed for N-2 and energized by a square-pipe jet singlet oxygen generator (JSOG). A cryosorption vacuum pump was used as the pressure recovery system for CO2 and N-2 buffer gases. The output power with CO2 was 27.3% lower than that with N-2, but the zeolite bed showed an adsorption capacity threefold higher for CO2 than for N-2 in the continuous operation with a Cl-2 flow rate of 155 mmol/s and a total flow rate of 430 +/- 3 mmol/s.

Similarity criteria in calculations of the energy characteristics of a cw oxygen - iodine laser
TL;DR: In this paper, the energy efficiency of a cw oxygen- iodine laser (OIL) was analyzed based on two similarity criteria, namely, on the ratio of the residence time of the gas mixture in the resonator to the characteristic time of extraction of the energy stored in singlet oxygen and iodine and on the gain-to-loss ratio Π.
