We fabricated an advanced transparent Yb-doped hexagonal fluorapatite ceramic with an average grain size of only 90 nm; we also demonstrated its laser oscillation. To the best of our knowledge, this is the smallest grain size for laser ceramics. The in-line transmittance was 86.1% at 1 µm for 0.79-mm-thick ceramics (corresponding to a loss coefficient of 0.45 cm-1). Although the ceramic crystal grains were randomly oriented, scattering at the grain boundary was suppressed because the grains were considerably smaller than the wavelength. This novel ceramic possesses both a fine microstructure and densification and is expected to be the foundation of many non-cubic laser ceramics.

高光学品质的非立方 Yb 3+掺杂 Ca 10 (PO 4 ) 6 F 2 (Yb:FAP) 激光陶瓷

我们制造了一种先进的透明掺镱六方氟磷灰石陶瓷,平均晶粒尺寸仅为 90 nm;我们还展示了它的激光振荡。据我们所知,这是激光陶瓷的最小晶粒尺寸。对于 0.79 毫米厚的陶瓷(对应于 0.45 厘米-1的损耗系数),1 µm 处的在线透射率为 86.1% 。尽管陶瓷晶粒是随机取向的,但由于晶粒远小于波长,因此抑制了晶界处的散射。这种新型陶瓷具有精细的微观结构和致密性,有望成为许多非立方激光陶瓷的基础。
