    摘要： Embodiments herein describe spectroscopy systems that provide frequency, amplitude, and power-stabilized light to a vapor cell. An optical signal can be split into two optical paths where a first optical path includes an AOM to perform frequency and amplitude modulation to generate a pump optical signal and a second optical path that includes a variable optical attenuator (VOA) for generating a probe optical signal. These optical signals can then be provided into a vapor cell (also referred to as a gas cell) to perform spectroscopy.

    摘要： Embodiments herein describe a continuous wave two-way optical time two-way transfer system. The embodiments herein lock a local frequency comb to a clock (e.g., optical/microwave atomic clock, Fabry-Perot optical reference cavity, etc.) in a local platform. The platform then generates two CW optical signals with different frequencies and locks those optical signals to the local frequency comb. The local platform then transmits its two CW optical signals to a remote platform and receives CW optical signals (having approximately the same frequencies as the two CW optical signals generated by the local platform) from the remote platform. Based on comparing its local CW optical signals with the received CW optical signals, the local platform can determine a timing deviation between its clock and a clock in the second platform.

    摘要： Embodiments herein described using a matched filter in a measurement device that includes an atomic sensor with a co-sensor. In one embodiment, the matched filter is a non-causal filter. Embodiments herein also describe a method for producing a matched filter by determining a filter transfer function from the transfer functions of the atomic sensor and the co-sensor. The method can be used to produce a matched filter that is non-causal but can also generate a causal filter for time sensitive applications.

    摘要： Embodiments herein describe spectroscopy systems that use an unmodulated reference optical signal to mitigate noise, or for other advantages. In one embodiment, the unmodulated reference optical signal is transmitted through the same vapor cell as a modulated pump optical signal. As such, the unmodulated reference optical signal experiences absorption by the vapor, which converts laser phase noise to amplitude noise like the other optical signals passing through the vapor cell. In one embodiment, the unmodulated reference optical signal has an optical path in the gas cell that is offset (or non-crossing) from the optical path of the modulated pump optical signal. The unmodulated reference optical signal allows removal or mitigation of the noise on the other optical signal.

    摘要： Embodiments herein describe techniques for designing a magnetic coil. The coil can include a coil mount where current-carrying wires are wrapped around the mount, or a current-carrying bar where the electric current flows through the part itself. Embodiments herein also describe non-planar magnetic coils for magneto-optical trap (MOTs).
