| Abstract (English): | The analysis of the surface ablation of the removal of lichens from stone by use of a free-running pulsed Er:YAG laser (erbium-doped yttrium, aluminium, garnet crystal) at a wavelength of 2.94 μm demonstrated the complete destruction of the lichen cell wall. In this paper these results are confirmed, and experiments are described which seek to determine the physical/chemical mechanism of the ablation process using pyrolysis gas chromatography-mass spectrometry (pyrolysis GC-MS), high-performance liquid chromatography (HPLC), Fourier transform infrared spectroscopy (FTIR) and fluorescence microscopy.

| Abstract (Spanish): | El análisis de la climinación o ablación del depósito superficial de líquenes en la piedra, mediante un láser pulsado de libre funcionamiento Er:YAG (itrio dopado con erbio, aluminio, cristal de granate) en una longitud de onda de 2.94 μm, demostró qne se había producido una completa destrucción de las paredes celulares de los líquenes. En este artículo se confirman estos resultados y se describen además determinados experimentos que intentan determinar los mecanismos fisico-químicos de los procesos de separación mediante cromatografía de gases por pirólisis-espectrometría de masas (pirólisis GC-MS), cromatografía de líquidos de alta resolución (HPLC), espectrometría infrarroja por transformada de Fourier (FTIR) y microscopía de fluorescencia.

| Abstract (French): | L'analyse de la surface d'ablation lors de l'élimination de lichens de la pierre par utilisation d'un laser pulsé relaxé de type Er : YAG (cristal de grenat, yttrium et aluminium dopé à l'erbium), à une longueur d'onde de 2,94 μm, a permis de vérifier la destruction complète de la membrane des cellules de lichen. Dans cet article, on confirme ces résultats et on décrit les expériences visant à déterminer le mécanisme physico-chimique du processus d'ablation en utilisant la chromatographie gazeuse par pyrolyse coupéc à la spectrométrie de masse (CG par pyrolyse-SM), la chromatographie liquide à haute performance (CLHP), la spectrométrie infrarouge a transformée de Fourier (IRTF) et la microscopie de fluorescence.

| Abstract (German): | Die Analyse des Oberflächenabtrages von Flechten auf Stein mit Hilfe eines gepulsten Er:YAG Lasers (Erbium dotiertes Yttrium, Aluminium, Granat Kristall) bei einer Wellenlänge von 2.94 μm zeigte eine vollständige Zerstörung der Zellwände der Flechten. In dieser Arbeit werden diese Ergebnisse erneut bestätigt, und Experimente durchgeführt, den phyikalisch-chemischen Mechanismus des Abtrages zu beschreiben. Dazu wurden Pyrolyse Gaschromatographie-Massenspectrometrie (Pyrolys GC-MS), Hochdruckflüissigkeitschromatographie (HPLC,), Fourier transform Infrarotspektroskopie (FTIR) und Fluoreszenzmi Kroscopie eingesetzt.
