The ionization and Coulomb explosion of homonuclear D n and T n (nϭ959-8007) and heteronuclear (D 2 O) n and (T 2 O) n (nϭ459-2171) clusters in very intense (Iϭ5ϫ10 14 -5ϫ10 18 W cm Ϫ2 ) laser fields is studied using classical dynamics simulations. The efficiency of the dϩd and dϩt nuclear fusion driven by the Coulomb explosion ͑NFDCE͒ is explored. The dϩd NFDCE of (D 2 O) n heteronuclear clusters is enhanced by energetic and kinematic effects for D ϩ , while for (T 2 O) n heteronuclear
more » ... the kinetic energy of T ϩ is dominated by energetic effects. The cluster size dependence of the fusion reaction yield has been established. The heteronuclear clusters provide considerably higher dϩd and dϩt fusion reaction yields than the homonuclear clusters of the same size. The clusters consisting of both D and T atoms can provide highly efficient dϩt fusion reactions.
