The mechanism and characteristics of the thermal effect of laser on energetic materials are analyzed from the aspects of theory, experiment and numerical calculation. The relationship between the critical value of laser ignition energy and laser power density, ambient temperature and other factors are also studied. Laser compared the photochemical action of energetic materials and photochemical ignition mechanism. Compared with the hot ignition, the photochemical ignition has a strong selectivity to the laser wavelength. The critical power and critical energy of the photochemical ignition are smaller
