A gigawatt laser‐induced Coulomb explosion has been observed in carbon disulphide (CS 2 ) clusters generating energetic, multiply charged [C] m+ ( m   = 1–4) and [S] n+ ( n   = 1–6) atomic ions of carbon and sulphur. The Coulomb explosion shows wavelength dependence. Comparison of these results with our earlier work shows that the polarizability and dipole moment might help in energy absorption from the laser field but they are not mandatory conditions for this low‐intensity Coulomb explosion. The results show that in a field of 10 9  W/cm 2 , absorption of 266 and 355 nm laser radiation by CS 2 clusters leads to multiphoton dissociation/ionization whereas at 532 nm the whole cluster explodes generating multiply charged atomic ions.
