Coulomb explosion of ammonia clusters induced by intense nanosecond laser at 532 and 1064nm: Wavelength dependence of the multicharged nitrogen ions

Abstract

The Coulomb explosion of ammonia clusters induced by nanosecond laser field with intensity in the range of 10(10)-10(12) W cm(-2) and wavelength of 532 and 1064 nm has been studied. N2+ and N3+ ions are the main multicharged ions at 532 nm, while He-like N5+ ion is the domain multicharged ion at 1064 nm.
