“…Recently, the 5S → 5P → 5D two-photon transition of rubidium was extensively studied [18] because of several merits including the strong absorption line owing to the large transition probability, the superior Doppler-free background caused by the small difference between the real energy level and the virtual energy level, and the potential application as a frequency standard in the 1.55 µm telecommunications band [19]. Research has also expanded to new areas, such as building a frequency standard [17], realization of artificial periodic structure [20], generation of the orbital angular momentum of light [21], or quantum repeater at telecommunications wavelengths [22].…”

“…An all fiber frequency standard for optical communication applications based on two-photon transition spectroscopy in rubidium at 778.1 nm was reported [29]. The frequency stabilization method of a diode laser that operates on the excited state transition of 87 Rb atoms was investigated and supposed to be a simple method to control the laser frequency [18]. Recently, our group realized a high signal-to-noise (SNR) TPTS at 778.1 nm with the intensity modulation method.…”

We present a laser frequency locking scheme for the high excited transition of rubidium, which cannot be directly referenced by atomic absorption spectroscopy. Double resonance optical pumping spectroscopy and two-photon transition spectroscopy of a 5S → 5P → 5D transition are obtained in a room temperature vapor cell and employed as the reference sources. An Allan deviation of 1.71 × 10 −12 at an averaging time of 2048 s with a residual frequency fluctuation of ±0.2 MHz over 7000 s is obtained by two-photon transition spectroscopy. The case of double resonance optical pumping spectroscopy presents an Allan deviation of 4.86 × 10 −12 at an averaging time of 2048 s with a residual frequency fluctuation of ±0.4 MHz over 7000 s. One distinct advantage of two-photon transition spectroscopy method is demonstrated by the analysis of the fast Fourier transform of error signal. A narrower full width at half-maximum of two-photon transition spectroscopy and a higher zero crossing slope by using a frequency modulation method lead to a better frequency stabilization. This work provides a technical basis for the laser frequency stabilization based on atomic and molecular transition spectroscopy, and it also supplies a new frequency standard for optical telecommunication applications.

“…In multi-level atomic systems coupled with several lasers, the excited-state transitions can also be used as locking signals with some variations on the techniques above. These include locks based on electromagnetically induced transparency (EIT) [33][34][35], fluorescence detection [36], and excited-state polarisation spectroscopy with [37] and without [38] a small magnetic field. As our experiments are done in the HPB regime, none of the aforementioned techniques are immediately suitable for our purposes.…”

Simultaneous two-photon resonant optical laser locking (STROLLing) in the hyperfine Paschen–Back regime

et al. 2018

View full text Add to dashboard Cite

We demonstrate a technique to lock simultaneously two laser frequencies to each step of a two-photon transition in the presence of a magnetic field sufficiently large to gain access to the hyperfine Paschen-Back regime. A ladder configuration with the 5, 5, and 5 terms in a thermal vapor of 87 atoms is used. The two lasers remain locked for more than 24 h. For the sum of the laser frequencies, which represents the stability of the two-photon lock, we measure a frequency instability of less than the Rb natural linewidth of 6 MHz for nearly all measured timescales.

“…The compensation field induces a scalar and tensor light shift on the 5P 3/2 excited state while its effect on the ground state is negligible. The compensation laser is offset-locked to the 5P 3/2 → 5D 5/2 transition using absorption spectroscopy [24], see supplementary material.…”

Coupling a single trapped atom to a whispering-gallery-mode microresonator

We demonstrate trapping of a single 85 Rb atom at a distance of 200 nm from the surface of a whispering-gallery-mode bottle microresonator. The atom is trapped in an optical potential, which is created by retroreflecting a red-detuned focused laser beam from the resonator surface. We counteract the trap-induced light shift of the atomic transition frequency by superposing a second laser beam with suitably chosen power and detuning. This allows us to observe a vacuum Rabi-splitting in the excitation spectrum of the coupled atom-resonator system. This first demonstration of stable and controlled interaction of a single atom with a whispering-gallery-mode in the strong coupling regime opens up the route towards the implementation of quantum protocols and applications that harvest the chiral atom-light coupling present in this class of resonators.
