Initiation of Explosion of Pentaerythritol Tetranitrate by Pulses of the First and Second Harmonics of a Neodymium Laser

It is shown that during initiation of explosion of pentaerythritol tetranitrate (PETN) by the second harmonic of a laser, the primary process of energy absorption is ionization of PETN molecules by the mechanism of two-photon absorption. Possibility of regulating the PETN sensitivity by adding nicke...

Description
Summary:It is shown that during initiation of explosion of pentaerythritol tetranitrate (PETN) by the second harmonic of a laser, the primary process of energy absorption is ionization of PETN molecules by the mechanism of two-photon absorption. Possibility of regulating the PETN sensitivity by adding nickel nanoparticles to laser irradiation is established.
