✦ Synopsis

Ionisation and dissociative ionisation of CSs by intense 532 nm radiation in the intermediate regime between tunnelling and multiphoton ionisation has been studied. The relative intensities of S, C+ and CS$ have been measured as a function of laser intensity over the range 4x lo'*-7X lOI W cm-'. S+ ions have a significantly lower saturation intensity than C+ and CS:. Comparison of the respective ionisation energies indicates that the intense laser field dissociates CS2 first, and the fragments are subsequently ion&d.
