Abstract
In ignition elements where the energy required to ignite the charge is produced using a laser source, the laser light is injected by means of an optical fiber or a laser optics system enabling the laser light to be focused onto the charge at the required intensity for ignition. Transmission losses and injection losses occur while the laser light is transmitted by means of optical devices or optical fibers. Known ignition devices are also complicated in terms of construction. According to the invention, the laser light source is a laser diode (3) and the explosive (4) that is to be ignited is arranged directly on the part (12) of the housing (8) of the laser diode (3) that allows the laser light (13) to pass through it.
