Initiation of Detonation by a Light Pulse in a Thin Charge of the VS-2 Pyrotechnic Composition

On the mechanism of ionization of atoms at compression of a substance by front of the converging shock wave

“…The detonation of the initiating layer of the PEC was carried out by the action of pulsed radiation from a neodymium glass laser (laser energy 0.17 J, radiation time 11 10 9 s at half-height of the laser pulse maximum; wavelength 1.06 10 6 m). To initiate simultaneously the entire surface of the open base of the PEC, the laser beam was expanded using a lens [33] to the layer diameter. The method for forming a plane detonation wave is reliable.…”

“…The method for forming a plane detonation wave is reliable. Evidence is a number of positive experimental results obtained during the formation of plane shock waves in the material under study directly by a plane detonation wave front at an angle of 0° relative to the surface of the material facing the striker [33,34], or by a detonation wave front sliding at an angle of 90° to the generatrix of the cylinder surface [35], or by the impact of a fl at plate accelerated by the products of the PEC explosion [36], including in problems of studying the nature of the fl ow of matter behind the front of the bow shock [37].…”
