Abstract

We explore the pressure evolution and structural dynamics of transient phase transitions in a microfluidic water jet after laser-induced dielectric breakdown. To this end, we use a combined approach of near-field holography with single femtosecond x-ray free-electron laser pulses and x-ray diffraction. During cavitation and jet breakup, we observe shock wave emission along the jet. The formation of the shockwave is accompanied by pronounced changes in the structure factor of water as an evidence by a shift in the water diffraction peak. This indicates a transition to a high density liquid structure induced by the transient pressure increase.
