【 摘 要 】

In this paper the initiation thresholds were measured and kinetics of decomposition was studied for pressed powders of FTDO (furasan-1,2,3,4-tetrazin-1,3-dioxide) at pulsed laser action by different laser wavelengths: 266 nm (zone-to-zone absorption), 532 nm (transparency range), 1.064 nm (transparency range) and 10600 nm (phonon absorption) that corresponds to absorption region (266 nm), transparency range (532 nm; 1064 nm) and phonon absorption (10600 nm) of these explosives.
