Description	A pilot study devoted to comparison of ablation crater formation on selected samples by 3 different laser sources: Yb-KGW laser with 1030 nm and pulse duration 350 fs, XUV laser emitting at 46.9 nm laser pulses with a duration of 1.7 ns and commonly used Nd:YAG laser with fundamental wavelength 1064 nm and higher harmonics, and typical pulse duration of 4.5 ns. Lasers sources were used to create craters into Cu, Fe, Zn, Sn, Pb, Si and brass sheets. The irradiance of the target with different lasers was kept constant, when it was possible. Different counts of pulses to observe the depth, shape and size of ablation craters were used. The feasibility of these LA sources for LIBS application will be discussed.
