## Description

- description: "Transparent ceramics of Nd3+-doped (Ca0.5Sr0.5)10(PO4)6F2 (CS-FAP),
    a solid\r\nsolution of hexagonal fluorapatite Ca10(PO4)6F2 (C-FAP) and Sr10(PO4)6F2
    (S-FAP), was\r\nsuccessfully fabricated. Laser oscillation from Nd:CS-FAP was
    demonstrated for the first time.\r\nThe ceramics consisted of fine grains with
    an average grain size of approximately 100 nm.\r\nDespite a non-cubic crystal
    structure, light scattering due to birefringence was small, and the\r\ntotal loss
    coefficient near 1 μm was approximately 0.5 cm−1. The full width at half maximum\r\n(FWHM)
    of the fluorescence spectra was about 3.5 nm (31 cm−1) at 1 μm and 6.4 nm (36
    cm−1)\r\nat 1.3 μm, respectively. They were substantially broader than those of
    C-FAP and S-FAP (both\r\napproximately 1 nm), resulting from lattice distortion
    due to solid solution formation. The\r\nfluorescence peak wavelengths and laser
    oscillation wavelengths (1061 nm and 1333 nm) were\r\nintermediate between those
    of C-FAP and S-FAP. The Ca to Sr ratio can be controlled, providing\r\ncompositional
    design flexibility and the potential of CS-FAP ceramics as novel ultrashort-pulse\r\nlaser
    materials."
