A Pr 3+ ‐doped transparent oxyfluoride glass‐ceramic containing Ca 5 ( PO 4 ) 3 F nanocrystals was prepared by melt quenching and subsequent thermal treatment. The crystallization phase and morphology of the Ca 5 ( PO 4 ) 3 F nanocrystals were investigated by X‐ray diffraction and transmission electron microscope, respectively. The volume fraction of the Ca 5 ( PO 4 ) 3 F nanocrystals in the glass‐ceramic is about 10% and the fraction of Pr 3+ ions incorporated into the Ca 5 ( PO 4 ) 3 F nanocrystals is about 22%. The peak absorption cross sections at 435 and 574 nm increase up to 128% and 132% after crystallization, respectively. The peak stimulated emission cross sections of the 3 P 0 → 3 H 4 blue laser channel and 3 P 0 → 3 F 2 red laser channel for the glass‐ceramic are 4.95 × 10 −20 and 29.8 × 10 −20 cm 2 , respectively. The spectral properties indicate that the glass‐ceramic is a potential visible laser material.
