论文摘要
激光稳定为真空间隙Fabry-Pérot光学参考腔表现出极低的噪声和高稳定性，线宽小于1 Hz。这些激光器可以随着可在大规模制造的紧凑，便携式腔的开发而扩展到新的应用和无处不在的使用。在这里，我们演示了一个8 ml体积的Fabry-Pérot腔，该腔构建了镜子，这些镜子在平版印刷上，用薄弱的镜子构成了100万。锁定到腔的激光器表现出相位噪声的限制，受腔热噪声的限制，偏移频率从1 Hz到$ \ $ \ $ 1 kHz，分数频率稳定性为7 $ \ times $ \ times $ 10 $^{ - 15} $在1秒。此外，使用微生物镜子的使用使我们能够扩大厘米尺寸腔的设计空间，我们探索将朝向2 ml或更少的腔体量推向腔体的噪音含义。
Lasers stabilized to vacuum-gap Fabry-Pérot optical reference cavities display extraordinarily low noise and high stability, with linewidths much less than 1 Hz. These lasers can expand into new applications and ubiquitous use with the development of compact, portable cavities that are manufacturable at scale. Here we demonstrate an 8 mL volume Fabry-Pérot cavity constructed with mirrors that are fabricated lithographically with finesse near 1 million. A laser locked to the cavity exhibits phase noise limited by the cavity thermal noise for offset frequencies ranging from 1 Hz to $\approx$ 1 kHz, with a fractional frequency stability of 7$\times$10$^{-15}$ at 1 second. Furthermore, the use of microfabricated mirrors allows us to expand the design space of centimeter-scale cavities, and we explore the noise implications of pushing towards cavity volumes of 2 mL or less.
