Optical characterization of Tm3+ in LiYF4 and LiLuF4 crystals

A comparative study of the optical properties of Tm3+ in LiYF4 (YLF) and LiLuF4 (LLF) crystals is presented. Room temperature polarized absorption spectra and fluorescence spectra for Tm3+ in LYF and LLF were measured and analysed. By applying the Judd--Ofelt approach, the intensity parameters Delta...

Zusammenfassung:	A comparative study of the optical properties of Tm3+ in LiYF4 (YLF) and LiLuF4 (LLF) crystals is presented. Room temperature polarized absorption spectra and fluorescence spectra for Tm3+ in LYF and LLF were measured and analysed. By applying the Judd--Ofelt approach, the intensity parameters Delta *W2,4,6 were calculated. The radiative transition rates, branching ratios and radiative lifetimes were also obtained. The results were analysed and compared between these two samples, indicating that both of them are favourable laser media.
