Fine-structure Raman interferometry with metastable barium for magnetically resilient inertial sensing
Masaki Nagamori, Hiromi Hatano, Toshiyuki Hosoya +3
Atom-interferometric quantum inertial sensors are promising candidates for inertial navigation systems owing to their high sensitivity and intrinsically low drift. However, their a…
Theoretical Proposal of a Digital Closed-Loop Thermal Atomic-Beam Interferometer for High-Bandwidth, Wide-Dynamic-Range, and Simultaneous Absolute Acceleration-Rotation Sensing
Tomoya Sato, Toshiyuki Hosoya, Martin Miranda +3
We present a theoretical proposal and simulation study of a digital closed-loop thermal atomic-beam interferometer for inertial navigation applications. The scheme synchronizes pha…
Sub-Recoil Transverse Momentum Width in a Cold Ytterbium Atomic Beam
Toshiyuki Hosoya, Tomoya Sato, Ryotaro Inoue +1
We demonstrate the generation of a slow ytterbium atomic beam with a transverse momentum width of times the photon recoil associated with Bragg diffraction, and a flux of…
Closed-loop measurements in an atom interferometer gyroscope with velocity-dependent phase-dispersion compensation
Tomoya Sato, Naoki Nishimura, Naoki Kaku +4
Atom interferometer-based gyroscopes are expected to have a wide range of applications due to their high sensitivity. However, their dynamic range is limited by dephasing caused by…
High-Flux Cold Ytterbium Atomic Beam Source Using Two-Dimensional Laser Cooling with Intercombination Transition
Toshiyuki Hosoya, Ryotaro Inoue, Tomoya Sato +1
We demonstrate a high-flux and low transverse temperature atomic beam of ytterbium by applying two-dimensional cooling using the intercom…
Measuring the branching ratios from the state to metastable states in europium
Yuki Miyazawa, Ryotaro Inoue, Keiji Nishida +2
We measure the branching ratios from the excited state to six metastable states of europium through fluorescence spectroscopy of an atomic beam. The sum of the s…
Injection locking of a high power ultraviolet laser diode for laser cooling of ytterbium atoms
Toshiyuki Hosoya, Martin Miranda, Ryotaro Inoue +1
We developed a high-power laser system at a wavelength of 399 nm for laser cooling of ytterbium atoms with ultraviolet laser diodes. The system is composed of an external cavity la…
