The results of a plasma jet analysis are presented during the deposition of calcium hydroxyapatite Ca₁₀(PO_4)₆(OH)₂ coatings on Ti-6Al-4V substrates via laser ablation of targets with a KrF excimer laser. The deposition was performed under an oxygen pressure of 10^-4 Torr in a vacuum chamber at room temperature. During the ablation process, emission spectra were recorded using two fast spectrophotometers in the 268-674 nm range. A comparative analysis of the spectroscopic data is performed, and the results of color image processing and the characteristics of the plasma jet propagation during ablation are estimated. Keywords: pulsed laser deposition, laser ablation, thin films, plasma jet, emission spectra.
