NF4BF4has been irradiated with a low-power CO2laser to produce reactive species which then initiate reactions in an ambient NF3-H2mixture. The laser-induced decomposition of NF4BF4in vacuum was measured as a function of laser power and energy. The laser-induced decomposition threshold was determined to be 40 mJ, which corresponds to a laser fluence of 20 J/cm2. This same value was determined for the initiation threshold of NF3-H2reactions via CO2laser irradiation of NF4BF4. Visible and infrared emissions were observed from initiated NF3-H2mixtures. This radiative technique has attractive features for initiating reactions in solid-gas systems.
