We present a laser system based on a 48 cm long optical glass resonator. The large size requires a sophisticated thermal control and optimized mounting design. A self-balancing mounting was essential to reliably reach sensitivities to acceleration of below Δν/ν<2×10(-10)/g in all directions. Furthermore, fiber noise cancellations from a common reference point near the laser diode to the cavity mirror and to additional user points (Sr clock and frequency comb) are implemented. Through comparison with other cavity-stabilized lasers and with a strontium lattice clock, instability of below 1×10(-16) at averaging times from 1 to 1000 s is revealed.
我们展示了一种基于48厘米长光学玻璃谐振器的激光系统。其大尺寸需要精密的热控制和优化的安装设计。自平衡安装对于在所有方向上可靠地达到低于Δν/ν<2×10(-10)/g的加速度灵敏度至关重要。此外，还实现了从激光二极管附近的公共参考点到腔镜以及到其他用户点（锶钟和频率梳）的光纤噪声消除。通过与其他腔稳定激光器和锶晶格钟进行比较，发现在1至1000秒的平均时间内不稳定性低于1×10(-16)。
