Abstract: The structure and the spectral-luminescent properties of CaF₂ — TmF₃ fluoride ceramics and single crystals are studied. AFM investigations revealed a layered nanostructure of grains, which was not observed in reference samples of single crystals. It is found that the spectral-luminescent properties of CaF₂ — TmF₃ ceramics and single crystals are similar. Lasing at the ³F₄ → ³H₆ transition of Tm³⁺ ions in CaF₂ — TmF₃ ceramics (wavelength 1898 nm) under diode pimping is obtained for the first time.

Keywords: fluoride laser ceramics, nanostructure, two-micron lasing.
