A cryogenic buffer gas beam source with in-situ ablation target replacement
Zhen Han, Zack Lasner, Collin Diver +11
The design and performance of a cryogenic buffer gas beam (CBGB) source with a load-lock system is presented. The ACME III electron electric dipole moment (eEDM) search experiment…
Geometry-dependent spectra and coherent-transient measurement of nearly degenerate four-wave mixing using two-photon resonance
Hideaki Hara, Yuki Miyamoto, Takahiro Hiraki +7
We study nearly degenerate four-wave mixing using a two-photon-allowed vibrational transition of parahydrogen. A signal photon is generated by a trigger photon and coherence among…
Coherent two-photon emission from hydrogen molecules excited by counter-propagating laser pulses
Takahiro Hiraki, Hideaki Hara, Yuki Miyamoto +7
We observed two-photon emission signals from the first vibrationally excited state of parahydrogen gas excited coherently by counter-propagating laser pulses. A single narrow-linew…
Externally triggered coherent two-photon emission from hydrogen molecules
Yuki Miyamoto, Hideaki Hara, Takahiko Masuda +6
We report coherent enhancement of two-photon emission from the excited vibrational state of molecular hydrogen triggered by irradiating mid-infrared pulses externally. We previousl…
Observation of coherent two-photon emission from the first vibrationally-excited state of hydrogen molecules
Yuki Miyamoto, Hideaki Hara, Susumu Kuma +10
In this paper, we describe an experiment which was conducted to explore the macro-coherent amplification mechanism using a two-photon emission process from the first vibrationally-…
Spin Dependent Collision of Ultracold Metastable Atoms
Satoshi Uetake, Ryo Murakami, John M. Doyle +1
Spin-polarized metastable atoms of ultracold ytterbium are trapped at high density and their inelastic collisional properties are measured. We reveal that in collisions of Yb(3P2)…
