Effect of background gas, sample angle and laser polarization on the enhancement effect of resonant laser ablation†
Abstract
The main characteristic of the resonant laser ablation (RLA) phenomenon is an enhancement in the number of atoms ablated from the surface when the ablation laser wavelength is tuned to match a gas phase transition of the analyte of interest. It has been suggested in the literature that the RLA phenomenon is probably based on radiation trapping with contributions from desorption induced by electronic transitions. In the present paper, a study was made of the effects of laser polarization, sample angle and the identity of the background gas on the enhancements observed during resonant
