Abstract

This article covers the developments in the field of laser ablation and highlights the current issues under investigation. Fundamental parameters such pulse width, wavelength, elemental and isotopic fractionation, the ablation mechanism, precision, and accuracy as well the the available software packages for calculation and manipulation of the data obtained by laser ablation are discussed. Ongoing research is focused on elemental-isotopic fractionation and on high-precision stable isotope ratio determinations and the use of femtosecond pulses for ablation. The recent results obtained using femtosecond pulses for ablation illustrate that this analytical technique is still under development.
