A downhole tool includes a plurality of mechanical components with some that move relative to others. The tool includes an annular charge cannister associated with the plurality of mechanical components that delivers a gas to move mechanical components. The annular charge cannister includes an annular chamber having a back wall, an interior sidewall, an exterior sidewall, and an open side opposite the back wall. The back wall and the interior sidewall and exterior sidewall form an interior space, and a power charge is disposed within the interior space of the annular chamber. An annular lid is sized and configured to mate with the open side of the annular chamber. The charge cannister may include an ignition port formed in the annular lid for receiving an igniter.

A laser ignition assembly comprises first and second mounting surfaces opposed to each other. A central cavity is formed through the surfaces and sized to receive energetic material therein. A vertical solder bridge is formed between the surfaces and an edge emitting laser diode disposed between the surfaces. The laser diode is oriented such that a light fluence therefrom is directed in a radial direction into the central cavity. The surfaces can be circuit boards, e.g., copper clad, rigid circuit boards, and have an annular shape. The central cavity can be further defined by an interboard gap between the surfaces. The ignition assembly can fit within a primer cup of a munition.

Embodiments of a low-voltage, non-primary explosive detonator (110) may include a detonator shell (120) having an open end (122), a closed end (124), and a hollow interior (125) between the open and closed ends. Some embodiments include a reinforcement area of the detonator shell. A pyrotechnical material is disposed within the hollow interior, and a main explosive load is disposed within the hollow interior in between the pyrotechnical material and the closed end. In some embodiments, one or both of the pyrotechnical material and the main explosive load may be multilayered, for example with a density gradient configured to accelerate eflagration. The detonator may further include a fuse head disposed at the open end and in proximity to the pyrotechnical material within the detonator shell.
