To quantify this phenomenon, we performed experiments in a standard mock explosive -compressed sucrose- avoiding the handling constraints of explosives. Because the medium is granular and optically opaque, we employed time-resolved synchrotron X-ray imaging to directly observe shock-induced structural evolution. A green nanosecond laser pulse serves as the shock driver. The generation of a shock wave is confirmed by ex-situ tomographic analysis, which also enables quantitative interpretation of the time-resolved data to determine the shock pressure (~\u20093.6 GPa) and propagation velocity (~\u2009Mach 4). Furthermore, doping with aluminum nanoparticles enhances laser absorption and increases the resulting shock pressure. These results demonstrate the potential of high-power laser pulses for initiation of detonation in secondary explosives and provide a pathway toward faster, optically-triggered detonator concepts.<\/jats:p>","DOI":"10.1038\/s41598-026-49885-2","type":"journal-article","created":{"date-parts":[[2026,6,9]],"date-time":"2026-06-09T09:06:59Z","timestamp":1780996019000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["High-speed radiography of laser-induced shock wave generation in a mock explosive"],"prefix":"10.1038","volume":"16","author":[{"given":"H.","family":"Lorent\u00e9","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Mouskeftaras","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Sollier","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.","family":"Lukic","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Rack","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"O.","family":"Uteza","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"Jumpertz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,6,9]]},"reference":[{"key":"49885_CR1","doi-asserted-by":"crossref","unstructured":"Galuga, J. & Bray, J.
