Abstract (en)

[origin: WO0243196A2] The invention relates to a laser emitter, in particular, for free space data transmission and/or weapon simulators, comprising a laser diode (11), generating a laser beam (10) from laser impulses and an emitter lens (13), arranged after the laser diode (11) in the beam path, for influencing the beam profile (15) and the intensity distribution in the beam profile (15). In order to achieve a high range with an effective area (16) of the laser beam (10) almost constant over distance, the emitter lens (13) is so arranged that the intensity in the beam profile (15) falls away, as a square of the separation (r), from a spatially limited intensity maximum in the centre of the profile out towards the profile edge.
