We perform a strong-field pump, weak-field probe transient absorption (TA) experiment that uses a microfluidic chip nozzle to produce a 2-micron thick water flatjet at room temperature. Both pulses are 6-fs and 800-nm, requiring a thinner liquid jet than previous experiments. This approach provides significantly better time resolution than any liquid water strong field TA experiments previously reported. The strong-field pump field-ionizes the water, then the weak-field probe arrives at a variable time delay to measure changes in the optical absorption of the water due to the ionization. We observe the time-dependent formation of the solvated electron, changes in the water refractive index, and plasma effects when the electron concentration is sufficiently high.
