| 111 | Method and device for initiation and ignition of explosive charges through self-destruction of a laser source | US10471459 | 2002-02-25 | US07204190B2 | 2007-04-17 | Owe Englund |
| 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. | ||||||

| The present invention is directed to a system having a plurality of capacitor discharge units (CDUs) that includes electrical bridge type detonators operatively coupled to respective explosives. A pulse charging circuit is adapted to provide a voltage for each respective capacitor in each CDU. Such capacitors are discharged through the electrical bridge type detonators upon receiving an optical signal to detonate respective operatively coupled explosives at substantially the same time. | ||||||
| 114 | Ignition element with a laser light source | US09763193 | 2001-04-13 | US06499404B1 | 2002-12-31 | Heinz Kern; Gerhard Kordel |
| 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. | ||||||

| 118 | Thin-film optical initiator | US09377190 | 1999-08-19 | US06276276B1 | 2001-08-21 | Kenneth L. Erickson |
| A thin-film optical initiator having an inert, transparent substrate, a reactive thin film, which can be either an explosive or a pyrotechnic, and a reflective thin film. The resultant thin-film optical initiator system also comprises a fiber-optic cable connected to a low-energy laser source, an output charge, and an initiator housing. The reactive thin film, which may contain very thin embedded layers or be a co-deposit of a light-absorbing material such as carbon, absorbs the incident laser light, is volumetrically heated, and explodes against the output charge, imparting about 5 to 20 times more energy than in the incident laser pulse. | ||||||
