      abstract     = {For the in situ application of LID (Laser-Induced
                      Desorption) as a space-resolved tritium retention diagnostic
                      in ITER, the desorption behaviour of co-deposited deuterium
                      (D) from beryllium (Be) layers is studied. In particular,
                      the desorption efficiency dependence on laser pulse
                      parameters is investigated for pulse durations of 1–20 ms
                      and absorbed energy densities up to 5 MJ m−2. For these
                      parameter scans homogenous Be/D layers were produced by High
                      Power Impulse Magnetron Sputtering, with 10 μm thickness
                      and 1.6 $at\%$ D. Almost $99\%$ of the initial D can be
                      desorbed with a single LID pulse. As the layers show a high
                      D desorption temperature (ca. 800 K) in slow Thermal
                      Desorption Spectrometry, an LID efficiency of only $50\%$ is
                      reached before Be melting. Microscopy reveals that in molten
                      regions holes are formed, which could serve as desorption
                      channels to facilitate gas release above the melting point.
                      Hill formation and cracking are further modifications, but
                      no layer destruction was observed in general.},
