A nuclear clock synchronized to Th
Beichen Huang, Gaowei Yan, Qi Xiao +37
Atomic clocks have made time and frequency the most precisely measured quantities in physics, progressing from microwave standards that realize the SI second to optical clocks with…
A continuous-wave vacuum ultraviolet laser for the nuclear clock
Qi Xiao, Gleb Penyazkov, Xiangliang Li +14
The exceptionally low-energy isomeric transition in Th at around 148.4 nm offers a unique opportunity for coherent nuclear control and the realisation of a nuclear clock. R…
Saturated absorption spectroscopy of buffer-gas-cooled Barium monofluoride molecules
Wenhao Bu, Yuhe Zhang, Qian Liang +2
We report an experimental investigation on the Doppler-free saturated absorption spectroscopy of buffer-gas-cooled Barium monofluoride (BaF) molecules in a 4~K cryogenic cell. The…
Doppler cooling of buffer-gas-cooled Barium monofluoride molecules
Yuhe Zhang, Zixuan Zeng, Qian Liang +2
We demonstrate one-dimensional Doppler cooling of a beam of buffer-gas cooled Barium monofluoride (BaF) molecules. The dependences of the cooling efficiency with the laser detuning…
A general Zeeman slower for type-II transitions and polar molecules
Qian Liang, Wenhao Bu, Yuhe Zhang +2
We proposed a general Zeeman slower scheme applicable to the majority of the laser-coolable molecules. Different from previous schemes, the key idea of our scheme lies in that the…
Laser cooling with adiabatic passage for diatomic molecules
Qian Liang, Tao Chen, Wenhao Bu +2
We present a magnetically enhanced laser cooling scheme applicable to multi-level type-II transitions and further diatomic molecules with adiabatic transfer. An angled magnetic fie…
Radiative deflection of a BaF molecular beam from the optical cycling
Tao Chen, Wenhao Bu, Bo Yan
We demonstrate a quasi optical cycling for the transition and a radiative force induced deflection on the buffer-gas cooled BaF molecular beam. The laser induce…
Cold collision and high-resolution spectroscopy of buffer gas cooled BaF Molecule
Wenhao Bu, Tao Chen, Guitao Lv +1
We reported a detailed experimental study of the cold collision of Barium monofluoride (BaF) with buffer gas and the high-resolution spectroscopy relevant with direct laser cooling…
Structures, Branching Ratios and Laser Cooling Scheme for 138BaF Molecule
Tao Chen, Wenhao Bu, Bo Yan
For laser cooling considerations, we have theoretically investigated the electronic, rovibrational and hypefine structures of BaF molecule. The highly diagonal Franck-Condon factor…
An in-situ method for measuring the non-linear response of a Fabry-Perot cavity
Wenhao Bu, Mengke Liu, Dizhou Xie +1
High finesse Fabry-Perot(FP) cavity is a very important frequency reference for laser stabiliza- tion, and is widely used for applications such as precision measurement, laser cool…
