A hybrid configuration of a heat-capacity laser (HCL) and a moving-slab laser (MSL) is proposed. Multiple volumes of solid-state laser material are sequentially diode-pumped and their energy extracted. When a volume reaches a maximum temperature after a “submagazine depth,” it is moved out of the pumping region into a cooling region, and a new volume is introduced. The total magazine depth equals the submagazine depth times the number of volumes. The design parameters are chosen to provide high duty factor operation, resulting in effective use of the diode arrays. The concept significantly reduces diode array cost and is considered enabling for many potential applications.
