Abstract
WE PROPOSE TO INVESTIGATE THE FEASIBILITY OF A NEW CHEMICAL LASER BASED ON THE (RED) 0.76 MICROMETERS O2 1SIGMA YIELDS O2 3SIGMA TRANSITION. THE O2 1SIGMA STATE IS PRODUCED BY AN ENERGY-POOLING REACTION (O2 1DELTA + O2 1DELTA YIELDS O2 1SIGMA + 3SIGMA(1)). THE O2 1DELTA ELECTRONIC EXCITED STATE IS PRODUCED BY PRIOR CHEMICAL REACTION. THE SINGLET OXYGEN (SOX) LASER IS AN ALTERNATIVE TO THE CHEMICAL OXYGEN-IODINE LASER (COIL), WHICH HAS DEMONSTRATED LASING AT 1.3 MICROMETERS FROM AN ATOMIC IODINE STATE COLLISIONALLY EXCITED BY O2 1DELTA. THE SOX LASER OFFERS THE POTENTIAL OF COMPARABLY HIGH ENERGY DENSITY, REASONABLE GAIN AND GOOD EFFICIENCY. THE MOST IMPORTANT FACTORS INFLUENCING THE EFFICIENCY OF THE PROPOSED LASER ARE THE RATE CONSTANT FOR ENERGY POOLING (EQ. 1) AND THE QUENCHING CONSTANT THAT REPRESENTS THE SUM OF ALL PROCESSES THAT DEACTIVATE O2 1SIGMA. THE OBJECTIVES OF THE PHASE I EFFORT ARE TO MEASURE THE RATE CONSTANT FOR QUENCHING OF O2 1SIGMA BY O2 1DELTA AND TO CONFIRM ACCEPTED VALUES FOR SEVERAL OTHER RATE CONSTANTS, INCLUDING THE POOLING REACTION (EQ. 1) AND QUENCHING OF BOTH O2 1SIGMA AND O2 1DELTA BY GROUND STATE OXYGEN. IF THE VALUES FOR RATE CONSTANTS OBTAINED IN PHASE I ARE FAVORABLE, WE EXPECT TO DEMONSTRATE THE SOX LASER IN PHASE II.
