Abstract

A theoretical model is developed for chemical generators producing O₂(¹(Delta) ) at high pressure. Such generators are especially important for supersonic chemical oxygen-iodine lasers. The model treats different types of generators, e.g., bubble column, film, aerosol, and jet generators. The main factor affecting the O₂(¹(Delta) ) yield under high pressure is liquid-phase quenching enhanced by depletion of HO₂^- ions near the gas/liquid interface. Simple analytical expressions are derived for the O₂(¹(Delta) ) yield at the exit of the generator. Output characteristics of different specific generators are calculated and compared with available experimental results. O₂(¹(Delta) ) yield > 0.5 can be achieved for oxygen pressure up to 50 Torr and flowrates of 3 mmol/cm²s. For equal velocities of the gas and the liquid the maximum flux of the energy carried by O₂(¹(Delta) ) for jet or aerosol generators reaches 200 W/cm². It can be increased by increasing the liquid velocity in the generator.
