Abstract

A long-life pyrotechnic lamp particularly suited for use in a compact, low-cost laser employing a solid-state laser rod which is pumped by the optical radiation of a pyrotechnic lamp employing the direct combustion of a metal in a flowing oxygen-containing atmosphere. The metal is supported on and heated to ignition by a graphite rod. The metal comprises a cylinder having a centered longitudinal bore adapted to receive the rod therein and has its outer surface serrated or finned to greatly increase the surface area. In one embodiment, the fins are helical about the outer surface. In another embodiment, the outer surface of the metal is longitudinally slit. In both cases, the metal is subsequently sliced into segments.
