Abstract

In solids and viscous liquids, irreversible ultrafast dynamics, such as high-intensity processes and photo-induced chemical reactions, have to date proven difficult to study spectroscopically. In low-viscosity liquids, such processes can be monitored with conventional ultrafast techniques, so long as the liquid is flowed fast enough that each set of laser pulses interrogates a new portion of the sample. Such an approach is not practical in solids or viscous liquids, however.
