We present a comparative study of the spectroscopic properties of Tm in several crystalline hosts: YAlO3,Y3Al5O12,La2Be2O5, and LiYF4. These materials were experimentally characterized in the spectral region accessible to laser diodes, especially in the context of advantages of pumping at 685 rather than 785 nm. Using the Fuchtbauer–Ladenburg equation, we also calculate the emission cross-section spectra from the experimentally measured fluorescence spectra, in the vicinity of the  3F43H6 and  3H413H5 transitions. The lifetimes of the  3F4– and  3H4– multiplets at room temperature were measured experimentally. We finally report, for the first time to our knowledge, absorption lines for different optical transitions of Tm in La2Be2O5.
