Towards quantum controlled initiation of explosives
- Los Alamos National Laboratory
As a first step toward understanding and controlling excited state dynamics in explosives, transient absorption spectra of Hexanitroazobenzene (HNAB) in acetone, Trinitroaniline (TNA) in acetone and Diaminoazoxyfurazan (DAAF) in dimethylsulfoxide (DMSO) were investigated in an ultrafast shaped pump/supercontinuum probe experiment for their dependence on single parameter control schemes. Two single parameter control methods, second order spectral phase (linear chirp) and the effect of pump energy on the amount of transmitted pump light were investigated. Novel transient absorption spectra were obtained for the three explosives. The spectral features found in the HNAB and TNA solutions had evidence of more complex control possibilities, while the spectral features of DAAF were dominated by intensity control.
