Description

Menlo Systems FC1500-ULNplus超低噪声光频梳是光钟的频率测量理想

“发条”。Menlo Systems 的全保偏figure9®模式锁定技术结合宽带激励元件

(>1MHz)支持载波包络偏移频率 (CEO)和重复频率的锁定以确保系统最佳性

能。随着对时间和频率稳定度和精度需求不断增长,对晶振单元和频率参考

的改进尤为必要。现今,稳定度最高的光钟依赖于窄带光学跃迁作为晶振

及作为发条的光学频率梳。通过将两个独立的FC1500-ULNplus在相位锁

定环外进行比对已证实,FC1500-ULNplus能够完全支持当今具有最高精度和稳定度

光钟系统。光梳-光梳比对作为出厂测试一个常规环节,成为每个系统在出厂验收期间质检

的重要组成部分,确保将振荡器的光谱纯度完美复制到客户所需波长处。

  • Microwave Ultrastable RF Output

    Product Code: Microwave

    Ultrastable RF output in the 1 MHz-10 GHz range. Utilizing a high-sensitive fast photodetector and a frequency divider where needed.

  • ORS Optical Reference System

    Product Code: ORS

    The ORS Optical Reference System consist of a CW laser locked to a stable high-finesse optical reference cavity made of ultra-low expansion (ULE) glass. It offers ultra-narrow linewidth (< 1Hz) and outstanding short time stability (<2 x 10-15) at wavelengths such as 657 nm, 689 nm, 698 nm, 729 nm, and many others from 500 nm to 1600 nm. By locking the FC1500-250-ULN to the ORS, the purity of this state-of-the-art optical reference can be transferred throughout the entire frequency comb spectrum.

    For more information: ORS

Analysis of the out of loop beat signal between two ULNplus combs at the Strontium clock transition frequency: The extremely low phase noise proves that the spectral purity is transfered to the target wavelength, which makes the ULNplus a unique clockwork for Strontium and other optical lattice clocks.
