AbstractThe photoionization of seeded benzene beam by 25 ns laser pulse at wavelengths of 266, 355 and 1064 nm has been studied by the time-of-flight mass spectrometry. The observed mass spectra at 266 run and 355 nm at intensities of 10(10) similar to 10(11) W/cm(2) indicate a multiphoton ionization and dissociation (MPID) process, in which C+, C2Hx+, C3Hx+, C4Hx+ and C6H6+ are main products. While at 1064 nm laser of similar intensities, the domain ion is C4+ which is produced from Coulomb explosion. The longer wavelength facilities the energy absorption rate during inverse bremsstrahlung, which leads to the resulting wavelength dependence of the multicharged atomic ions.
