Birefringent atomic vapor laser lock in a hollow cathode lamp
Takumi Sato, Yusuke Hayakawa, Naohiro Okamoto +3
We report a robust method of stabilizing a laser to the frequency of an atomic transition using a hollow cathode lamp. In contrast to the standard dichroic atomic vapor laser lock…
Alkali ion-to-neutral atom converter for the magneto-optical trap of a radioactive isotope
Hirokazu Kawamura, Ken-ichi Harada, Tomoya Sato +12
We have developed a unique neutralizer device that uses an yttrium target surrounded by a platinum wall to magneto-optically trap radioactive atoms. In general, the radioactive nuc…
An optical lattice based method for precise measurements of atomic parity violation
A. Kastberg, T. Aoki, B. K. Sahoo +2
We propose a method for measuring parity violation in neutral atoms. It is an adaptation of a seminal work by Fortson [Phys. Rev. Lett. {\bf 70}, 2383 (1993)], proposing a scheme f…
Doppler-free spectroscopy of metastable Sr atoms using a hollow cathode lamp
Yusuke Hayakawa, Takumi Sato, Chika Watanabe +2
We report on the demonstration of Doppler-free spectroscopy of metastable Sr atoms using a hollow cathode lamp (HCL). We employed a custom Sr HCL which is filled with a mixture of…
A simplified 461-nm laser system using blue laser diodes and a hollow cathode lamp for laser cooling of Sr
Yosuke Shimada, Yuko Chida, Nozomi Ohtsubo +2
We develop a simplified light source at 461 nm for laser cooling of Sr without frequency-doubling crystals but with blue laser diodes. An anti-reflection coated blue laser diode in…
Photoionization loss in simultaneous magneto-optical trapping of Rb and Sr
Takatoshi Aoki, Yuki Yamanaka, Makoto Takeuchi +2
We demonstrate the simultaneous magneto-optical trapping (MOT) of Rb and Sr and examine the characteristic loss of Rb in the MOT due to photoionization by the cooling laser for Sr.…
Buffer gas-assisted polarization spectroscopy of 6Li
Nozomi Ohtsubo, Takatoshi Aoki, Yoshio Torii
We report on the demonstration of Doppler-free polarization spectroscopy of the D2 line of 6Li atoms. Counterintuitively, the presence of an Ar buffer gas, in a certain pressure ra…
Laser Phase and Frequency Stabilization Using Atomic Coherence
Yoshio Torii, Hideyasu Tashiro, Nozomi Ohtsubo +1
We present a novel and simple method of stabilizing the laser phase and frequency by polarization spectroscopy of an atomic vapor. In analogy to the Pound-Drever-Hall method, which…
