Abstract
Multifunctional Pr3+:YPO4 single crystals were investigated by high-resolution optical Fourier spectroscopy. The analysis of the transmission and luminescence spectra allowed us to supplement information on crystal-field levels of the Pr3+ ion. Shapes of spectral lines corresponding to transitions from the ground state to the degenerated Γ5 crystal-field levels reveal the hyperfine structure and unambiguously point to the presence of random lattice deformations. The experimentally observed line shapes were successfully modeled and the halfwidth of the distribution function of random lattice deformations was determined. The lines with frequencies 4308 cm−1 and 9680 cm−1 are most sensitive to deformations and can be used to control the quality of YPO4 single crystals intended for applications in modern quantum technologies.
