In this work, the modes of synthesizing copper nanoparticles for use in an optical initiation system were proposed. The optimal sizes of the copper particles in the pentaerythritol tetranitrate were estimated, for use as a cup of the optical detonator on the rst and the second harmonics of the Nd:Yag laser. For the rst harmonic of the Nd:Yag, laser the absorptivity maximum was 0.097 and the particles radius was 98 nm, for the second harmonic, the absorptivity maximum rose more than in 34 times, and it was equal to 3.29 and the copper particles radius was 30 nm. Comparison of the calculated critical energy densities shows that pentaerythritol tetranitrate, which contains the copper nanoparticles, must be signi cantly more sensitive ( 29 times) to the second harmonic than to the rst. The modes of synthesis for copper nanoparticles of the required size were determined and tested.
