Notes:
An experimental device using a laser diode is described. The laser diode is coupled with a 100 μm diameter optical fiber. Lasering times are about one ms and the energy of the pulse ranges from 0.5 mJ to 5 mJ. Output power provided by optical fiber is about 0.5 W and the wavelength of radiation is 820 nm. Before each shot the pulse energy is measured by means of a joule meter. It allows a very accurate determination of the amount of energy transferred to the solid explosive. A small reactor containing about 40 mg of explosive is used. It allows to initiate combustion with a direct contact between the output of an optical fiber and the solid explosive. Three pyrotechnic compounds were tested and tests have shown that it is possible to ignite Zr/KClO4 and Zr/PbCrO4 mixtures. Experimental results are discussed and compared with numerical simulations presented in Part I.
