The presented results of measuring gold and silver nanoparticles parameters were ob-
tained by the method of pulsed laser ablation in liquid. We used different optical spectral
methods and electron microscopy to carry out measurements. For the synthesis of nano-
particles we chose the second harmonic of Nd:YAG laser with a 532 nm wavelength, and
irradiation of femtosecond laser S-PulseHR (wavelength 1030 nm). As a qualitative re-
sult we present the absorption spectra of the nanoparticles and nanoparticle pictures.
Keywords: laser ablation, nanoparticles, synthesis of nanoparticles, absorption spectra.
