Abstract
A laser diode apparatus for initiating explosives or other pyrotechnic devices that has capability of checking both the laser diode operation and the optical fiber continuity between the laser diode source and the explosives required to be detonated. Power isolation circuits are provided to control the flow of current to the laser diode, also isolation filters are used to allow only the command signals to initiate the firing circuits employed.
