“…Given the limitations of the modern powerful pulse lasers suitable for initiation, a certain amount of luck is required for satisfying this condition. Hence, it is not surprising that the first experiments to evidence a possibility of the resonance photoinitiation regime were performed only recently. − This article presents an extended analysis of these phenomena in the context of the most recent developments in the field.…”

“…Explosives could be made that are relatively stable to thermal and shock insults but are sensitive to laser excitation through photochemical initiation. While the photoinitiation of conventional energetic materials has long been studied, − only recently have materials been designed to optimize the absorption of light − at easily accessible laser wavelengths. In this paper, we detail measurement of the photochemistry of several new tetrazine − based photoactive high explosives.…”

High explosives that are photoactive, i.e., can be initiated with light, offer significant advantages in reduced potential for accidental electrical initiation. We examined a series of structurally related tetrazine based photoactive high explosive materials to detail their photochemical and photophysical properties. Using photobleaching infrared absorption, we determined quantum yields of photochemistry for nanosecond pulsed excitation at 355 and 532 nm. Changes in mass spectrometry during laser irradiation in vacuum measured the evolution of gaseous products. Fluorescence spectra, quantum yields, and lifetimes were measured to observe radiative channels of energy decay that compete with photochemistry. For the 6 materials studied, quantum yields of photochemistry ranged from <10(-5) to 0.03 and quantum yield of fluorescence ranged from <10(-3) to 0.33. In all cases, the photoexcitation nonradiatively relaxed primarily to heat, appropriate for supporting photothermal initiation processes. The photochemistry observed was dominated by ring scission of the tetrazine, but there was evidence of more extensive multistep reactions as well.
