Abstract : The surfaces of laser-irradiated gun propellants have been examined by scanning electron microscopy (SEM) and Fourier Transform Infrared (FTIR) microscopy. The results suggest that the laser-irradiated surfaces exhibit chemical and physical changes similar to those exhibited by the burned surfaces of propellant samples, the combustion of which have been quenched short of completion. Some possible implications of this for combustion and for the modelling of laser ignition are discussed. jg p.3
