A laser initiation system for measuring the ignition properties of pyrotechnics and explosives is described. The laser source is a continuous wave (cw) argon laser operating in the visible wavelength region. A shutter-chopper system converts the cw beam to a pulsed beam. The 514.5 nm line with a chopped pulse width of 3 milliseconds was used to ignite the three pyrotechnic compositions TiH/sub x//KClO/sub 4/(x = 0.2, 0.65, 1.65). In an argon atmosphere of 0.79 MPa, the ignition thresholds with a focused Gaussian beam diameter of 66 microns were 554, 866, and 657 microjoules for the three respective compositions. The ignition properties of TiH/sub x//KClO/sub 4/ are found to be strongly dependent on pressure. Rapid changes in the reflectivity of the sample surface also occur within microseconds after application of the laser pulse. 12 refs., 5 figs., 1 tab.
