We present a gauge to characterize explosively-generated shocks in solids where traditional gauges are not applicable. The laser-pumped optical fiber gauge embedded in Modified Gap Test cylinders correctly determined the shock's arrival time and was sensitive to pressure. Although the gauge requires hydrocode modeling before quantitative pressure accuracy can be assessed, the gauge can qualitatively compare the performance of explosives.
