Abstract
A stable kilohertz (kHz) rate laser ablation/desorption supersonic molecular beam source for use in kHz rate laser experiments was discussed. The source was based based upon strong nonresonant interaction of a dithering laser focus with a rotating and translating solid rod. The kHz laser ablation of a high temperature refractory metal (niobium) for use in studied of metal clusters was also demonstrated. The kHz laser desorption and jet cooling of an involatile biomolecule (the DNA based guanine) for use in spectroscopic and dynamical studies was described.
