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…

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…
