Abstract
Theoretical study of spectroscopic properties of LiNbO3:Er3+ crystal in the wavelength range of 1470–1635 nm was carried out taking into account the Stark structure of the optical spectrum of the impurity ion. Wave functions of the Stark sublevels of both ground \({}^{4}{{I}_{{15/2}}}\) and first excited \({}^{4}{{I}_{{13/2}}}\) manifolds of the Er3+ ion were constructed in the LSJM representation, line strengths induced by indirect electric-dipole inter-Stark transitions were computed, and the main spectroscopic characteristics of emission and absorption spectra of impurity ion were determined.
