英文摘要Experimental investigations on the dissociation and ionization processes of NO2 in intense fields at wavelengths of 810, 405 and 270 nm, are presented. The ratios of NO2+/NO+ are found to be independent of the laser intensity at these three wavelengths, but show strong dependence on the wavelengths. Longer wavelength produces a larger parent-ion yield in comparison with 405 nm. Peak profiles of all the fragment ions clearly show little kinetic energy releasing during the dissociation. Fragment ions are suggested to be produced from dissociation of the field ionized parent ions. Our results indicate that laser pulse wavelengths are the most important parameters in ionization-fragmen- tation process of polyatomic molecules in intense field other than the laser intensity.
