Abstract
In an embodiment, a photoinitiation apparatus includes: a set of illumination sources or elements configured for outputting optical energy; a body structure having a proximal body structure portion confining a proximal volume of explosive medium, an intermediate body structure portion confining an intermediate volume of explosive medium, and a distal body structure portion confining a distal volume of explosive medium, wherein the proximal volume of explosive medium is optically coupled to portions of the first volume of explosive medium, at least one of the proximal volume of explosive medium and the distal volume of explosive medium is a tertiary explosive medium, and (a) the body structure does not carry a primary explosive composition and does not carry a secondary explosive composition, and/or (b) each of the proximal, intermediate, and distal volumes of explosive media has an initiation sensitivity that is less than cyclotrimethylenetrinitramine (RDX) based explosive compositions.
