Abstract
This work reports on the optical properties of Cr${}^{3+}$ ions in the pseudoternary system InF${}_{3}$-GdF${}_{3}$-GaF${}_{3}$. Linear properties, investigated through absorption and emission spectra, provide information on the crystal field, the frequency, and number of phonons emitted during the absorption to the ${}^{4}{T}_{2}$ band and the emission to the ${}^{4}{A}_{2}$ ground state, and the Fano antiresonance line shape in the vicinity of the ${}^{4}{A}_{2}{\ensuremath{\rightarrow}}^{2}E$ transition. A study of the nonlinear refractive index as a function of the wavelength, carried out with the $Z$-scan technique, provides spectroscopic data about electronic transitions starting from the excited state.
