Spectroscopic Properties of LiNbO3:Tm3+ Crystal in the 1650–1970 nm Wavelength Range

详细

Taking into account the Stark structure of optical spectrum of the impurity ion, the theoretical study of spectroscopic properties of LiNbO₃:Tm³⁺ crystal in the wavelength range of 1650–1970 nm was carried out. The wave functions of the Stark sublevels of both ground ³H₆ and the first excited ³F₄ manifolds of the Tm³⁺ ion were constructed in the LSJM-representation, the 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.
