This paper considers the development of high-power laser-DEW systems required to achieve
significant effects on potential targets. The emphasis is on the progress with the technology and
systems required to support the out-of-band approach needed to achieve a robust defeat mechanism;
various laser-induced effects are discussed. The advantages and disadvantages of laser-based directedenergy
weapon (DEW) systems will be reviewed.
Evolution of laser-source technology is reviewed, with a particular emphasis on modern approaches
such as the various novel-source investigations, including fibre-bundle devices. The paper discusses
some of the research studies that are underway that may make this type of laser-weapon system viable.
Some of the challenges currently faced by laser-based DEW systems are considered in this paper.
