标题： Dual-wavelength laser source for onboard atom interferometry

摘要： 我们提出了一种紧凑且稳定的双波长激光源，用于使用两种不同原子种类的机载原子干涉测量。 它基于锁频到飞秒光学频率梳的倍频电信激光器。 我们利用光纤电信技术的成熟性，减少固有不稳定的自由空间光学元件数量，并使装置对振动和热波动具有免疫力。 该光源提供了原子干涉测量所需的频率灵活性和相位稳定性，并可轻松适应其他冷原子实验。 我们通过在抛物线飞行中实现首次双物种K-Rb磁光捕获，证明了其鲁棒性。 显示英文摘要

摘要： We present a compact and stable dual-wavelength laser source for onboard atom interferometry with two different atomic species. It is based on frequency-doubled telecom lasers locked on a femtosecond optical frequency comb. We take advantage of the maturity of fiber telecom technology to reduce the number of free-space optical components which are intrinsically less stable, and to make the setup immune to vibrations and thermal fluctuations. The source provides the frequency agility and phase stability required for atom interferometry and can easily be adapted to other cold atom experiments. We have shown its robustness by achieving the first dual-species K-Rb magneto optical trap in microgravity during parabolic flights.
