Abstract: In the interaction of intense ultra-short laser pulses with micrometer sized droplets, the droplets are ionised and transformed into a plasma. In this work, the laser-droplet-interaction is studied based on the plasma emission in the extreme ultraviolet (EUV) spectral range. The spectroscopy of the emission allows for analysing the plasma state and the interaction sequence. Applying shaped laser pulses, the excitation is adapted to the plasma dynamics resulting in an enhanced EUV yield.
