Simulation of laser heat absorbing inclusions in a transparent matrix of explosive material is carried out. The inclusions are spherical particles with R0 radius ranging from 10{-5} to 10{-2} cm. The duration of the laser pulse varies from 10{-9} to 10{-3} s and allows investigating process in both adiabatic and quasi–stationary heating modes. It has been found that the duration of laser pulse affects the maximum heating temperature for particles with a specific radius. A remarkable thing is that the temperature drastically decreases if the absorption cross section and small size of inclusions are taken into account. It leads to heat reduction in a thermal center, which is formed nearby a small–sized inclusion, and shows strongly decreased reactive capacity of explosive decomposition.
