摘要: Femtosecond laser-field-induced dissociation and explosion of polyatomic molecules methane methanol were experimentally investigated by using a time-of-flight mass spectrometer chirped pulse amplifier laser. Both linearly polarized circularly femtosecond laser pulses used. The intensity varied from 6×1013 to 3×1015 W cm-2. Strong molecular ions, singly charged fragmental ions highly atomic observed for both methanol. had similar dependence on compared with the ions. This indicated that ionization inner-valence electron led formation excited rapidly dissociated into evidence Coulomb explosion. kinetic energies carbon almost zero relatively large was concerted process all bonds in broken simultaneously.
