Název v původním jazyce

A Comparative Study of Laser-Ablation of Selected Targets by ns Nd:YAG, fs Yb-KGW and Capillary-Discharge Based XUV Lasers for Laser-Induced Breakdown Spectroscopy

Popis výsledku v původním jazyce

Laser-ablation (LA) is used in several analytical techniques such as Laser-Induced Breakdown Spectroscopy (LIBS) or laser-ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The most commonly used lasers for these applications are Nd:YAG with wavelengths ranging from 1064 nm down to 213 nm, or excimer lasers in the UV range. Laser irradiance, pulse duration, wavelength, and focal spot size are the most important parameters of laser that influence the laser ablation and hence the analysisof different samples. Extremely short-duration (fs) laser pulses can be used to create regular ablation craters without the crater rim formed by melted material typically in ns ablation. Lasers with shorter wavelengths can be convenient for creation of small-diameter ablation craters, which can be important e.g. for high-resolution mapping [1]. Here we report on the outcomes in a pilot study devoted to comparison of ablation crater formation on selected samples by 3 different laser sourc
