Abstract
A theoretical study of the spectroscopic properties of the low-phonon LaF3:Er3+ crystals determining their laser capabilities in the mid-infrared wavelength range (2.62–4.97 μm) was carried out. The wave functions of the Stark sublevels of 4S3/2, 4F9/2, 4I9/2, 4I11/2, and 4I13/2 of Er3+ ion are constructed by the LSJM-representation. The line strengths of the indirect electric dipole and magnetic dipole inter-Stark transitions are computed and the main spectroscopic and kinetic characteristics of the optical spectrum of the impurity ion are determined.
