我们报告了CombSat的环境鉴定与性能，CombSat是一种双光频梳载荷，设计用于在低地球轨道上的12U立方星上部署。该载荷集成了两个自参考的200 MHz混合光纤-波导频率梳、一个窄线宽光学参考、一个外差拍频探测单元以及基于FPGA的控制电子设备，总质量为8.3千克，体积为5.7升，标称功耗为21瓦。我们描述了系统的机械、热和抗辐射设计特性，并展示了根据NASA通用环境验证标准进行的随机振动、存储温度循环和热真空测试的结果。我们表明，关键梳齿性能指标，包括振荡器和放大器输出功率、frep、fCEO和fopt信噪比以及积分相位噪声，在环境暴露后仍保持在规格范围内，并讨论了观察到的故障模式以及提高鲁棒性的设计修改。这些结果表明，紧凑、低功耗、完全稳定、自主的双梳系统可以在立方星平台上进行工程化和鉴定以用于太空飞行，为未来低成本基于梳齿的空间应用提供了一条前进道路。
英文摘要
We report the environmental qualification and performance of CombSat, a dual optical frequency comb payload designed for deployment on a 12U CubeSat in low Earth orbit. The payload integrates two self-referenced, 200 MHz hybrid fiber-waveguide frequency combs, a narrow-linewidth optical reference, a heterodyne beat detection unit, and FPGA-based control electronics in a total mass of 8.3 kg and volume of 5.7 L, and nominal power consumption of 21W. We describe the mechanical, thermal, and radiation-tolerant design features of the system and present the results of random vibration, storage temperature cycling, and thermal-vacuum testing conducted in accordance with NASA's General Environmental Verification Standard. We show that key comb performance metrics including oscillator and amplifier output power, frep, fCEO, and fopt signal-to-noise ratios, and integrated phase noise, remain within specification after environmental exposure, and we discuss observed failure modes and design modifications that improved robustness. These results demonstrate that compact, low power, fully stabilized, autonomous dual-comb systems can be engineered and qualified for spaceflight on CubeSat platforms, providing a path forward for future low-cost comb-based space applications.
