The thermal effect mechanism and characteristics of laser upon energetic materials were analyzed based on theory, experimental and numerical calculations. The relationships between the critical value of laser ignition and laser power density, and ambient temperature were investigated. The comparison between thermal effect and photochemical effect of laser has been made. Compared with thermal ignition, the photochemical ignition has higher selectivity on the wavelength of laser. And the critical power and critical energy are relatively low.
