ULTRAVIOLET AND VACUUM UILTRAVIOLET STIMULATED EMISSION IRRADIATOR

摘要

PURPOSE: To enhance the operational efficiency and output by employing, as a light source, a nitrogen laser causing stimulated emission of a specified wave length from a laser medium containing nitrogen by generating a population inversion between C-B levels of nitrogen molecule during discharge between cathode and anode thereby increasing the generation rate of ozone. ;CONSTITUTION: A gas containing oxygen molecules or oxygen atoms and an oxygen compound is irradiated by a light source, i.e., a vacuum ultraviolet stimulated emission irradiator. The light source comprises a nitrogen laser causing stimulated emission of 337.1nm wavelength by generating population inversion between C-B levels of nitrogen molecule in a laser medium during discharge between cathode and anode. This constitution realizes an ozone generator having high generation rate and enhances the efficiency of nitrogen laser because double gas piping, chemical eliminator, and scrubber can be eliminated.;COPYRIGHT: (C)1995,JPO
