The effect of high energy laser pulses on single wall carbon nanotubes (SWNT) is studied by a non-equilibrium quantum mechanical model. For the studied laser parameters, we find ablation thresholds that vary between 1.9 eV/atom and 2.3 eV/atom. For zigzag tubes a linear increase of damage thresholds as function of diameter is observed. For armchair tubes, a stability maximum is found at the (10, 10) SWNT. We find that below but close to the damage threshold the nanotubes show the presence of standing waves.
