摘要：

We report a new kind of multiphoton dissociation in intense laser fields. H2+ molecular ions were formed in above-threshold ionization of H2 gas by intense 532-nm, 100-ps laser pulses. Observations suggest that multiphoton couplings soften the molecular bond, resulting in dissociation at laser intensities over 50 TW/cm2. The ion-dissociation spectra have multiple peaks caused by multiphoton transitions during dissociation of H2+. © 1990 The American Physical Society.
