晶体光学腔是当今最先进的超稳激光器的基础。在我们之前的硅腔工作的基础上，我们现在实现了6 cm长的硅腔冷却到4 K的基本热噪声限制稳定性，从0.8 s到80 s达到6.5 x 10（-17）。我们还报告的第一次，尽我们所知，一个明确的线性依赖入射光功率的腔频率漂移。在40 nW的发射功率下获得了-3 x 10（-19）/s的最低分数频率漂移，在没有光功率的情况下外推漂移接近于零。这些演示提供了一个有希望的方向，以达到一个新的性能域的稳定激光器，稳定性优于1 × 10（-17）和分数线性漂移低于1 × 10（-19）/s。(c)根据OSA开放获取出版协议的条款，2019年美国光学学会
Crystalline optical cavities are the foundation of today's state-of-the-art ultrastable lasers. Building on our previous silicon cavity effort, we now achieve the fundamental thermal-noise-limited stability for a 6 cm long silicon cavity cooled to 4 K, reaching 6.5 x 10(-17) from 0.8 s to 80 s. We also report for the first time, to the best of our knowledge, a clear linear dependence of the cavity frequency drift on incident optical power. The lowest fractional frequency drift of -3 x 10(-19)/s is attained at a transmitted power of 40 nW, with an extrapolated drift approaching zero in the absence of optical power. These demonstrations provide a promising direction to reach a new performance domain for stable lasers, with stability better than 1 x 10(-17) and fractional linear drift below 1 x 10(-19)/s.
