Query: Laser-Ranging Long Baseline Differential Atom Interferometers for Space   High sensitivity differential atom interferometers are promising for
precision measurements in science frontiers in space, including gravity field
mapping for Earth science studies and gravitational wave detection. We propose
a new configuration of twin atom interferometers connected by a laser ranging
interferometer (LRI-AI) to provide precise information of the displacements
between the two AI reference mirrors and a means to phase-lock the two
independent interferometer lasers over long distances, thereby further
enhancing the feasibility of long baseline differential atom interferometers.
We show that a properly implemented LRI-AI can achieve equivalent functionality
to the conventional differential atom interferometer measurement system. LRI-AI
isolates the laser requirements for atom interferometers and for optical phase
readout between distant locations, thus enabling optimized allocation of
available laser power within a limited physical size and resource budget. A
unique aspect of LRI-AI also enables extended dynamic range of differential
signals and the highest possible effective data rate.
