Abstract: A window which is transparent to radiation in the visible, optical and nearnfrared range but not transparent to the radiation of a laser, is protected against distruction or damage by the laser radiation. For this purpose the window itself is constructed of at least two layers of solid optical material which is also transparent to the high energy laser radiation. These layers form a cooling channel through which a gaseous or liquid coolant flows. The coolant is transparent to the visible and near infrared range, but opaque to the laser radiation.

Abstract: A system for automatically firing or discharing a weapon, such as a mine, comprises acoustical sensors for the preliminary adjustment and firing of the weapon. An optical sensor is used in conjunction with the acoustical sensors. In a first step, prior to the first acoustical target acquisition, the target background is optically scanned to store first optical image values defining an optical image of the target background to determine a firing range and a firing horizon. Thereafter, an acoustical ranging is performed for the target acquisition. Then the optical scanning and storing is repeated with regard to a firing horizon and when a target approaches the firing horizon, to provide second optical image values which are compared with the first image values to provide, by signal differentiation, proof of the presence of a target at the firing horizon. The resulting signal is used to control the weapon. The steps of optical scanning, signal storing, and comparing may be repeated for a target zone, which is larger than the target, whereby a target profile or silhouette is produced. The respective electrical signal is used for the fine adjustment of the weapon prior to firing by the target presence signal.

Abstract: The present method relates to exciting a gas dynamic CO.sub.2 laser, especially at high stagnation temperatures above 2500.degree. K and at a combustion chamber pressure above 50 bar. A liquid fuel and a liquid oxidizer are injected into the combustion chamber at these operating parameters and the produced laser gas is caused to flow through a Laval nozzle into a resonator. The flow cross sectional area of the Laval nozzle adjacent to the resonator is at least 100 times larger than the flow cross sectional area adjacent to the nozzle neck facing the combustion chamber. The flow of the laser gas through this nozzle cools the gas to about 300.degree. K, whereby an inversion state is produced. The laser for performing this type of operation has a combustion chamber connected through the above mentioned nozzle to a resonator which in turn is connected to a diffuser. A tank for liquid fuel and a tank for a liquid oxidizer are connected to the respective injection nozzles of the combustion chamber, whereby the respective conduits preferably extend through cooling jackets of the combustion chamber of the diffuser.
