- Аннотация: Abstract: The absorption spectra in the near-IR range for several samples energetic material were studied. Heating of explosives of different classes by near-IR laser radiation (0.98 μm, 1.55 μm, and 1.94 μm) delivered by optical fiber was studied. The process of laser heating was studied for samples obtained by pressing powdered explosives and for single grown explosives crystals. It was shown that the initial rate of tempera-ture rises at the center of the laser spot when exposed to explosives samples is pro-portional to the laser radiation power. It has been established that the efficiency of laser heating depends not only on its density, heat capacity and focusing of laser ra-diation, but also on the scattering properties of the material. It has been shown that the efficiency of laser heating for pressed explosives samples is 2-5 times greater than the efficiency for samples in the form of an individual crystal. It is shown that the efficiency of laser heating for compounds containing N-H bonds at wavelengths of 1.56 μm to 50-100 times higher than at 1.94 and 0.98 μm. Keywords: near-IR, laser radiation, energetic material, heating
