“…Ablation with high-peak-power laser pulses provides another method for igniting or detonating materials. A laser pulse of 10 mJ over 8 ns at 532 nm was used to ablate aluminium inside a stoichiometric acetylene-oxygen atmosphere, initiating a detonation from the pressure generated by ablation [105]. Shock wave acceleration is also demonstrated by a laser-supported detonation wave, which involves irradiating plasma from an energetic reaction or explosion to greatly increase pressure in a localised region and enhancing the shock wave propagation [106].…”

Primers are used to reliably initiate a secondary explosive in a wide range of industrial and defence applications. However, established primer technologies pose both direct and indirect risks to health and safety. This review analyses a new generation of primer materials and ignition control mechanisms that have been developed to address these risks in firearms. Electrically or optically initiated metal, oxide and semiconductor-based devices show promise as alternatives for heavy metal percussive primers. The prospects for wider use of low-cost, safe, reliable and non-toxic primers are discussed in view of these developments.
