Abstract
The present invention relates to a new method, based on laser technology, of initiating explosive charges (6, 10, 17, 30), and a device which is intended for initiating explosives and in accordance with said method functions according to entirely new principles. The basic idea underlying the invention is to ignite the explosive charge concerned not as previously proposed by means of the radiation emitted from a laser but by way of self-destruction or overheating of a laser source (2, 11, 18, 25, 33) assembled together with the explosive charge (6, 10, 17, 30). In this regard, the aim is to cause the laser source to melt down or explode and, in connection with this, to initiate the explosive. With the present invention, it has suddenly become possible to use even very small laser sources of the mini or micro type for triggering explosive charges where it was previously necessary to use very powerful laser sources for the same purpose.
