New singlet oxygen generator for chemical oxygen-iodine lasers.

Experiments have been carried out to investigate a new method for generating O2(1Δ) with long-time operation of an efficient chemical oxygen-iodine laser system in mind. An impinging-jet nozzle was utilized to atomize a H2O2-KOH solution so that the alkaline H2O2/Cl2 reaction might occur in droplet-gas phase with high excitation efficiency. Experimental results indicate that the present generator can yield as high as 80% of O2(1Δ) with reasonable O2 flow rate. [ABSTRACT FROM AUTHOR]
