We describe and analyze the selective (resonance) laser-induced initiation of chemical decomposition reactions in pentaerythritol tetranitrate (PETN, C5H8N4O12) propose a potential mechanism for phenomenon. On basis our experiments, photoinitiation PETN is two-stage process that comprised optical excitation molecule with an activation energy 1.17 eV (1060 nm) by neodymium phosphate glass laser followed thermal excited state barrier 0.4 eV. also illustrate small efficiency absorption at this...
The ignition of different metamorphic grade coal particles by microsecond laser pulses (laser wavelength 1064 nm, pulse duration 120 μs, maximum energy per 1.3 J) was studied. Three stages with characteristic thresholds and durations combustion were revealed. fraction the absorbed flame thermal decomposition products determined; reflection absorption coefficients measured at each stage. Ignition established taking into account products, coefficient. At first stage, reactive microprotrusions...
