XUV spectroscopy on argon micro droplets in intense NIR laser fields — •Robert Irsig, Lev Kazak, Josef Tiggesbäumker, and Karl-Heinz Meiwes-Broer — Universität Rostock, Institut für Physik, Universitätsplatz 3, 18051 Rostock, Germany

We investigate the emission of soft x-ray radiation from liquid micro-sized argon droplets. The droplets are irradiated by ultra-short intense laser pulses with a center wavelength at 810nm. Due to efficient heating, highly charged ions with a characteristic plasma emission pattern are produced. With the use of a home-build flat-field XUV spectrometer, various atomic transitions can be identified allowing to study the nanoplasma properties. We present first results of the influence of the laser pulse parameters such as pulse length and pulse energy on the XUV emission.
