The interaction of a dense plasma with short laser pulses (ns) is investigated. The dense plasma is created using a low-current hollow-cathode-triggered discharge. This configuration generates a dense plasma with an electron density of ne 10 17 cm 3 . Spectra are taken in the extreme ultraviolet (EUV) spectral range from11-18 nm to estimate the temperature. The interaction between plasma and laser beam as a longitudinally pumped light source is discussed. The required properties of the plasma,

It is shown, that the generation of double pulses in the extrem ultraviolet spectral range is possible by reheating the residuals of an expanding dense plasma with a short laser pulse.
