Features of the plasma induced in water and ethanol jets under the action of strong subpicosecond IR pulses

Single-pulse scheme and time-resolved experiments are implemented to explore the plasma formation in water and ethanol liquid jets. The measured dependences of the plasma reflection on the pump pulse energy and duration indicate the strong influence of intensity variation. Furthermore, ethanol demonstrates almost 2-fold higher reflectivity in comparison to water. Time-resolved experiments and corresponding analysis provide the insight into the electron density dynamics by measuring the reflection of laser pump and its third harmonic.
