Abstract: An autonomous weapon system including weapon (9) and weapon mounting system (7, 8) operable to point the weapon (9) in accordance with input control signals. The weapon system includes a sensor (2) to acquire images and other data from a target zone and an image processor (3) to process acquired image data and identify potential targets (1) according to predetermined target identification criteria. Targeting system (4, 5) provides input control signals to the weapon mounting system (7, 8) to point the weapon (9) for firing at potential targets (1). A control system operates targeting system (4, 5) and fires the weapon (9) at selected targets (1) according to a predetermined of rules of engagement. The rules of engagement include combat, peacekeeping or policing scenarios. Remotely located operator (10) may amend the rules of engagement, or override the control system as required.

Abstract: An apparatus and method for transmitting a hazardous electromagnetic beam (10). A hazardous beam (10) and a non-hazardous beam (12) are generated and directed along respective paths which are substantially parallel and either at least partially coincident or in close proximity so that an object will traverse the path of the non-hazardous beam (12) immediately before it is impinged by the hazardous beam (10). Any disturbance of the non-hazardous beam (12) by an object is detected and the hazardous beam (10) is disabled in response to a predetermined disturbance.

Abstract: A solid state laser beam generating system includes a solid state laser which produces a laser beam having a wavelength outside the eyesafe range of 1.5 .mu.m to 1.8 .mu.m. A converter including a non-linear structure is used to convert the laser beam to a beam having a wavelength within the eyesafe range. The non-linear structure has three defined principal axes and the input laser beam to the structure travels in a direction offset from one of the principal axes by an angle greater than 2.degree..
