Experimental study on influence of cut current tail on xenon flashlamp work performance

As radiation sources for pumping solid state lasers, xenon flashlamp is a most important optical device in inertial confinement fusion. Experimental study on cutting current tail was carried out. The influences on discharge channel, temperature rise of the flashlamp outside surface, vibration caused by shock wave, fluorescence of neodymium glass were measured. Without the current tail, the effect of plasma on xenon flashlamp inner surface was weakened and the temperature rise of flashlamp outside surface reduced. Meanwhile, cutting more current tail had no effect on shock wave and would lower the output of neodymium fluorescence.
