In the field of laser spectroscopy the laser systems have evolved to highly precise measurement devices, covering the wavelength range from infrared to ultra violet. The ion beams from non-volatile substances on the other hand are often produced by surface ionization devices, which mostly allow for the ion beams from alkali and earth alkali metals and inhibit the study of other interesting elements (e.g. refractory elements). Conventional laser ablation ion sources expand the region of available elements, but their ion beams have large emittances. We present the current status of a combined He buffered laser ablation ion source with an electrode funnel for spatial confinement and the He gas for transportation and cooling of the ions. This ion source will combine the high variability of target materials from laser ablation with a small emittance ion beam and the possibility of bunching due to the funnel system.
