Abstract
A high precision, high power laser-radar system whose output beamwidth can be varied from a divergent to a convergent mode thus allowing for target acquisition, its high precision tracking and ultimately its destruction is described. Essentially the invention comprises an optical detector and an optical transmitter consisting of a steerable, large diameter, coherently packed, single mode optical fibre bundle, one end of which is compacted and optically polished to act as the transmitting aperture of the said laser-radar system while the other end of the said fibre bundle is unbound, with each individual fibre, or a small group of such fibres being optically coupled to one of many laser pulse amplifiers forming a large array of such amplifiers required to produce the transmitted laser output pulse energy.
