“…MAGIS-100, a next generation quantum sensing project at Fermilab, USA, is a 100-meter vertically-arranged atom interferometer. It uses Menlo Systems' complete quantum laser system comprising an ultrastable laser and an optical frequency comb as reference and laser sources for the strontium atom optical clock, and for the manipulation and detection of the atomic states [14].…”

This White Paper describes the operating principle, technical details, and performance of the Menlo Systems ORS Ultrastable Laser System. It gives a general overview of applications for ultrastable lasers, with specific use cases of Menlo Systems’ ORS systems. A more detailed presentation of an application using a novel approach for clock comparisons [1] demonstrates the capabilities of a commercial ultrastable laser system to perform state-of-the-art measurements, and the potential for future field applications

“…36 Software-defined sensing is realized with an agile RF and laser system capable of creating the necessary tailored light pulses with high fidelity. Indeed, this is the only hardware-level innovation 37,38 required in order to realize this form of sensing, as all other operational advances described here are achieved in software. Specifically, time-domain laser pulses are produced by driving a single AOM with the combined outputs of two phase-coherent DDS channels.…”

Quantum sensors based on cold atoms have enormous potential to unlock new capabilities in GPS-denied navigation, civil engineering, intelligence, and Earth observation. But operating these devices in realistic environments is currently extremely challenging, and for the most part the advantages of choosing a quantum sensor over a conventional alternative are lost in the transition from laboratory to noisy field-based environments. In this work, we demonstrate for the first time in hardware that tailored light pulses, designed and implemented in software using robust control techniques, can substantially mitigate some of the most nefarious effects in a Bragg atom interferometer. We show experimentally that embedding robust control into sensor operation can improve the signal-to-noise ratio of a state-of-the-art Bragg-pulse cold-atom interferometric sensor by a factor of 4× under ideal conditions. In the presence of laser-intensity noise that varies up to 20% from shot-to-shot, commensurate with common platform vibrations, we show experimentally that using the same robust control solutions preserves fringe visibility with minimal degradation while the utility of the primitive Gaussian pulses collapses, delivering an at least 8× improvement in phase-estimation uncertainty compared with primitive pulse schemes. Across all observations, robust control delivers better performance in a noisy environment than the native hardware performance with primitive pulses under approximately ideal conditions. Finally, building on this demonstration we present a validated theoretical concept to extend this performance improvement to compact devices using concatenated sequences of robust pulses designed to enhance the sensor's scale factor. Time-domain simulations reveal up to 10× performance enhancement in the presence of realistic atomic-cloud effects at 102ℏk momentum separation. These results show for the first time that software-defined quantum sensor operation can deliver useful performance in environmental regimes where primitive operation is impossible, providing a pathway to augment the performance of current and next generation portable cold-atom inertial sensors in real fielded settings.
