Abstract: We report on the high-resolution Fourier spectroscopy study of KY$_3$F$_{10}$:Pr$^{3+}$ crystals. The analysis of the transmission and luminescence spectra allowed us to refine and supplement the information on the crystal-field levels of the Pr$^{3+}$ ion. The value of the hyperfine splitting of the ground state of Pr$^{3+}$ in the KY$_3$F$_{10}$ cubic host is estimated. The observed shape of the spectral lines indicates the presence of defects in the sample under study.

Keywords: KY$_3$F$_{10}$:Pr$^{3+}$ crystal, Fourier spectroscopy, transmission and luminescence spectra.
