光回音壁微谐振腔在微光子学和非线性光学中具有非常低的阈值功率。在这里，我们提出的细节，超高Q回音壁模式谐振器的制造由CO2激光车床加工的熔融石英棒。谐振腔的制作时间小于1 min，光学品质因数超过Q = 1 × 10（9）。所演示的谐振器直径在170 μ m和8 mm之间的范围内（自由频谱范围在390 GHz和8 GHz之间）。使用这些微谐振器，观察到各种光学非线性，包括拉曼散射，布里渊散射，和四波混频。
Optical whispering-gallery microresonators are useful tools in microphotonics and non-linear optics at very low threshold powers. Here, we present details about the fabrication of ultra-high-Q whispering-gallery-mode resonators made by CO2-laser lathe machining of fused-quartz rods. The resonators can be fabricated in less than 1 min and the obtained optical quality factors exceed Q = 1 x 10(9). Demonstrated resonator diameters are in the range between 170 mu m and 8mm (free spectral ranges between 390 GHz and 8 GHz). Using these microresonators, a variety of optical nonlinearities are observed, including Raman scattering, Brillouin scattering, and four-wave mixing.
