An explosive device comprises an explosive charge and an initiator, the initiator having a discharge lamp optically coupled with said explosive charge and connected to a voltage source via a first switch. According to the invention said discharge lamp has a series resistor shunted via a second switch which is open before and closed when the explosive charge is initiated. The glow discharge evoked through said series resistor cannot initiate the explosive charge, but it shortens the time delay of the avalanche discharge and makes it independent of the stochastic natural ionization.
