    sintering

## Description

- description: "Transparent Er-doped Y2O3 ceramics were fabricated using the spark
    plasma sintering (SPS) technique without any sintering additives to achieve fine-grained
    midinfrared laser ceramics. The average grain size of ceramics was typically 300
    nm and their in-line optical transmittance in the 2.7 μm mid-infrared range reached
    approximately 99% of the theoretical value. The fluorescence spectra and lifetimes
    confirmed that the ceramics fabricated using SPS exhibited emission characteristics
    nearly identical to those fabricated using other sintering techniques. Despite
    the\r\nnumerous pores in the ceramics and considerably reduced transmittance at
    an excitation wavelength of 976 nm (approximately 90% of the theoretical value),
    a successful laser oscillation at 2.7 μm in the mid-infrared region was achieved.
    To the best of our knowledge, this is the first report on mid-infrared laser operation
    for finegrained ceramics having grain sizes below 500 nm. We believe that this
    study will contribute to further improvements in the optical properties and development
    of finegrained transparent ceramics as new laser materials, particularly non-cubic
    materials."
