Abstract:

Theoretical study of spectroscopic properties of LiNbO3:Tm3+ crystal in the wavelength range of 1650–1970 nm was carried out taking into account the Stark structure of optical spectrum of the impurity ion. Wave functions of the Stark sublevels of both ground 3H6 and first excited 3F4 manifolds of the Tm3+ ion were constructed in LSJM-representation, line strengths induced by indirect electric-dipole transitions were calculated, and the main spectroscopic characteristics of emission and absorption spectra of impurity ion were determined.
