Apparatus for and method of providing population inversion
Abstract
Abstract A METHOD OF AND APPARATUS FOR PRODUCING A POPULATION INVERSION BY EXPANSION THROUGH A NOZZLE AND INTO A CHAM BER, A PREFERABLY HOT EQUILIBRUIM GAS HAVING VARIOUS INTERNAL STATES WHICH HAVE DIFFERENT RELAXION TIMES, THE RELAXATION TIMES SUFFICIENTLY SEPARATED THAT THE UPPER LASER LEVEL RELAXATION TIME IS LONG COMPARED TO THE EXPANSION TIME AND THE LOWER LASER LEVEL RELAXATION TIME IS SHORT COMPARED TO THE EXPANSION TIME. THE EQUILIBRUIM GAS IS A MIXTURE OF A POLYATOMIC LASER GAS HAVING AN UPPER LASER LEVEL, A LOWER LASER LEVEL AND A GROUND STATE, AND AT LEAST ONE AUXILIARY GAS HAVING A VIBRATIONAL ENERGY LEVEL RESONANT WITH THE UPPER LASER LEVEL OF THE LASER GAS. THE AUXILLIARY GAS FUNCTIONS TO INCREASE THE EFFECTIVE RELAXATION TIME OF THE UPPER LASER LEVEL. THE HEATED MIXTURE MAY BE SUPPLIED BY TRANSFER HEATING OF THE GAS CONSTITUENTS OR BY DIRECT COMBUSION OF SUITABLE FUELS.
