Abstract

We report a significant improvement of the finesse and quality factor of a calcium fluoride whispering gallery mode optical resonator achieved with iterative thermal annealing. The initial and final values of the resonator finesse are F(i) approximately 5 x 10(5) and F(f) >/= 10(7) respectively. The measurements are conducted at room temperature in the laboratory atmosphere.

摘要

我们报告了通过迭代热退火实现的氟化钙回音壁模式光学谐振器的精细度和品质因数的显著提高。谐振器精细度的初始值和最终值分别为F(i)约5×10⁵和F(f)≥10⁷。测量是在实验室环境中的室温下进行的。
