Abstract

A directed energy weapon includes a number of laser units, each including a fiber laser generating an output beam with a power of at least 1 kW from a fiber, an objective lens arrangement for focusing the output beam into a focused beam directed towards a target, and a fine adjustment mechanism for adjusting a direction of the focused beam. A beam deflector arrangement is deployed to deflect a portion of the focused beam from each laser unit as a deflected beam in a direction in predefined relation to a direction of the focused beam. An angle sensing unit generates an output indicative of a current direction of said deflected beam for each of said laser units. A controller actuates the fine adjustment mechanisms based on the output from the angle sensing unit to maintain a desired relative alignment between directions of the focused beams.
