<title>Solid-state high-energy laser</title>

Abstract

This paper describes a high-energy laser (HEL) concept based on a disk-type solid-state laser operating in active mirror mode. The gain medium disks have high-performance real-time cooling that allows the laser to operate continuously. This configuration of the laser shows excellent scalability to high-average power required for directed energy applications and can be integrated into a simple, compact, lightweight, and affordable unit. The paper also discusses engineering concepts for integrated HEL, power-size-weight scaling model, as well as options for prime power and thermal management.
