Initiation of PETN explosion by the second harmonic pulse of a neodymium laser

The explosion of PETN of density 1.73 g/cm 3 was first initiated by the second-harmonic pulse of a Q-switched neodymium laser. It is shown that the primary process of energy absorption in this case is PETN molecule ionization involving two-photon absorption. The critical initiation energy density co...

Zusammenfassung:The explosion of PETN of density 1.73 g/cm 3 was first initiated by the second-harmonic pulse of a Q-switched neodymium laser. It is shown that the primary process of energy absorption in this case is PETN molecule ionization involving two-photon absorption. The critical initiation energy density corresponding to a 50-% probability of explosion is 12.3 J/cm 2 .
