论文摘要
我们在这封信中报告说，自动冰冻蓝宝石振荡器的出色频率稳定性表现出色的频率噪声底部以下2e-16接近1,000 s的整合时间和长期的Allan偏差（ADEV），受到1E-18/SQR（TAU）的随机步行过程的限制。该级别的频率稳定性资格要求实施与超稳定频率参考和AD HOQ平均和相关方法相关的复杂仪器。
We report in this letter the outstanding frequency stability performances of an autonomous cryogenique sapphire oscillator presenting a flicker frequency noise floor below 2e-16 near 1,000 s of integration time and a long term Allan Deviation (ADEV) limited by a random walk process of 1e-18/sqr(tau). The frequency stability qualification at this level called for the implementation of sophisticated instrumentation associated with ultra-stable frequency references and ad hoq averaging and correlation methods.
