We achieved a low-cost and small-sized Rb optical frequency standard based on 85Rb 5S1/2 → 6P3/2 transition with 10-15 stability, which is comparable with that of the best 532 nm I2 optical frequency standards. In this system, we directly lock the 420 nm diode laser on the 5S1/2 F = 3 → 6P3/2 F' = 4 hyperfine transition line without an additional(More)
Partly subjected to the stability of optical frequency source, the magnetic dipole and electric quadrupole hyperfine constants of the <sup>85</sup>Rb 6P<inf>3/2</inf> State have been reported to be 8.163(4) MHz and 8.191(27) MHz, respectively. To pursue the higher precision, here we have constructed two more robust <sup>85</sup>Rb spectrometers with a(More)
We present the design and performance characterization of a Faraday laser directly lasing on the Rb 1529 nm transition (Rb, 5P 3/2 - 4D 5/2) with high stability, narrow spectral linewidth and low cost. This system does not need an additional frequency-stabilized pump laser as a prerequisite to preparing Rb atom from 5S to 5P excited state. Just by using a(More)
