V originále
An acoustic signal was used for the internal standardization of laser induced breakdown spectroscopy (LIBS) of a glazed wall tile. For the LIBS analyses, 1064 nm and 532 nm wavelengths of the Nd:YAG laser were utilized. The tile was depth profiled by a single-spot ablation from the glaze into the substrate. Some lines of major elements Si(I) 252.418, Si(I) 252.851, Al(I) 257.509, Cr(I) 295.368, Al(I) 309.271 nm and Ti(II) 334.904 nm were monitored. The decrease in the optical emissions during the ablation was successfully compensated for by normalization to the square power of the acoustic signal in the interval of 290-340 nm. This approach failed for the lines between 250-270 nm. The results were the same for both lasing wavelengths despite different irradiances. The acquired profiles are in good agreement with the reference X-ray fluorescence measurement.

Akustický signál byl použit jako vnitřní standard při spektroskopii laserem vybuzeného mikroplazmatu (LIBS)glazovaných dlaždic. Experiment byl proveden s 1064 a 532 nm zářením Nd:YAG laseru ablací do bodu přes glazuru do střepu pro emisní čáry vybraných majoritních prvků: Si(I) 252.418, Si(I) 252.851, Al(I) 257.509, Cr(I) 295.368, Al(I) 309.271 nm a Ti(II) 334.904 nm. Pokles optické emise během ablace byl úspěšně kompenzován normalizací na druhou mocninu akustického signálu v intervalu vlnových délek 290-340 nm. To se však nedařilo pro interval 250-270 nm. Výsledky byly stejné pro obě vlnové délky laseru, byť byly použity rozdílné iradiace. Takto naměřené hloubkové profily jsou v souladu s referenčním měřením rentgenofluorescencí.
