【 摘 要 】

The goal of this paper is experimental study of the mechanism of initiation of secondary explosives (SE) by short laser pulse. Laser initiation of SE is much more difficult in comparison with initiation of primary explosives. Using of some special methods is typically requested to realize laser initiation of SE: using of porous SE, putting it in a closed envelope, and using some optically dense additives. In this paper we consider interaction of laser pulse with open surface of non-porous, optically uniform SE. Only pure chemical methods were used to control the light sensitivity of SE. Implementation of the method of laser initiation is reduced to the optimization of composition and molecular structure of the explosives, along with the optimization of the laser pulse (its duration, energy density and wavelength).
