Ion emission from argon microdroplets exposed by ultrashort intense laser pulses — •Lev Kazak, Robert Irsig, Josef Tiggesbäumker, and Karl-Heinz Meiwes-Broer — Insitute of Physics, University of Rostock, Universitätsplatz 3, 18051 Rostock, Germany
The liquid jets are attractive targets for laser-generated plasma investigation. From the one side it gives a great opportunity to study the properties of warm dense matter, from the other side they are interesting as possible candidate of X-ray and extreme ultraviolet (XUV) light sources. In the present study we concentrate on the ionization and heating of the microdroplets. The kinetic energies of the ions emitted from the droplets are simultaneously measured by field-free time-of-flight spectrometers located in laser propagation and counter-propagation directions. First results show a strong asymmetry. Ions with higher recoil energy are emitted predominately in the direction opposite to the laser propagation. The impact of the laser pulse parameters will be discussed.
