Abstract : The Air Force Phillips Laboratory is interested in developing a new class of laser device operating in the near infrared for electric optic countermeasure missions. One candidate for such a device is a chemically driven atomic bromine laser operating on the transition at 2.7 micrometers. It may be possible to produce excited bromine atoms by energy transfer from singlet oxygen in a manner similar to the Chemical Oxygen Iodine Laser (COIL). The COIL is based on an energy transfer scheme where the energy is stored in the metastable O2 and is transferred to atomic iodine in a near resonant and rapid collisional process. A great deal of information is available on the gas phase kinetics of the COIL devices. A similar device based on atomic bromine may be possible, but the prospects for development of this type of system depend critically on the rates of energy transfer from singlet oxygen to bromine atoms. These rates are dependent on molecular oxygen and other species within the laser.
