                      successfully for plasma-wall interaction studies in several
                      fusion devices and post-mortem analyses of plasma-facing
                      materials. However, the quantitative as well as qualitative
                      analysis of low hydrogen isotope contents in tungsten
                      plasma-facing components is still challenging. A promising
                      approach to increase the optical signal in laser-induced
                      breakdown spectroscopy is to apply a second laser pulse to
                      the laser-produced plasma. We present two setups for post
                      mortem plasma-facing component analyses using different
                      laser pulse properties and different excitation geometries.
                      The enhancement factors and changes in spectral line shapes
                      for double pulse compared to single pulse laser-induced
                      breakdown spectroscopy are presented.},
