英文摘要: Fragmentation of H-2 in femtosecond laser field is studied by using velocity map ion imaging method and 70 fs laser at 405 nm and 810 nm from 0.3 to 3.0 x 10(14) W/cm(2). Angular distributions from Coulomb explosion are independent of the laser wavelengths and intensities, which means the explosion starts from the same electronic state. Angular distributions from dissociation channels in the 810 nm laser field broaden with the laser intensity. Lobe structures in angular distributions from Coulomb explosion and above threshold dissociation channels are reported. Fine structures in the distribution of internuclear distances are observed.
