Se determinaron los umbrales de ablación láser de los metales cobre, oro y plata para la radiación láser de 1064 nm de un láser Nd:YAG de nanosegundos utilizándose la técnica fotoacústica pulsada para registrar las señales fotoacústicas producidas debido a la interacción del metal con los pulsos láser. Dichas señales se analizaron mediante correlación estándar y los cambios en la amplitud fotoacústica conforme aumento la fluencia láser. Los resultados indican que las señales fotoacústicas son muy sensibles a cambios físicos que experimenta una muestra solida debido a la interacción con pulsos láser, pudiendo diferenciarse claramente el cambio del régimen termoelástico al de ablación y por consiguiente el umbral de ablación. Los valores obtenidos para la fluencia umbral fueron: (1.71±0.08) J/cm2 para el cobre, (1.65±0.09) J/cm2 para el oro y (1.15±0.05) J/cm2 para la plata.
The laser ablation thresholds of the copper, gold and silver metals were determined for the laser radiation of 1064 nm of a nanosecond Nd: YAG laser using the pulsed photoacoustic technique to record the photoacoustic signals produced due to the interaction of the metal with the laser pulses. These signals were analyzed using the standard correlation and changes in the photoacoustic amplitude as the laser fluence increased. The results indicate that the photoacoustic signals are very sensitive to physical changes that a solid sample experiences due to the interaction with laser pulses, being able to clearly differentiate the change from the thermoelastic to the ablation regime and consequently the ablation threshold. The values obtained for the threshold fluence were: (1.71±0.08) J/cm2 for copper, (1.65±0.09) J/cm2 for gold and (1.15±0.05) J/cm2 for silver.
