“…A 459 nm laser stabilized to the Cs 6 S 1/2 ( F = 4) − 7 P 1/2 ( F = 3) transition by the saturated absorption spectroscopy (SAS) pumps the Cs atoms inside a 10 cm-long quartz cell. The pumping laser corresponds to a weak transition whereafter the spontaneous decay of the excited state will occur via multiple intermediate states, and the analogous energy structure has been studied in various systems 34 – 37 . After pumping, the Cs atoms are population inverted between 7 S 1/2 ( F = 4) and 6 P 3/2 ( F = 5) states 38 .…”

Taking advantages of ultra-narrow bandwidth and high noise rejection performance of the Faraday anomalous dispersion optical filter (FADOF), simultaneously with the coherent amplification of atomic stimulated emission, we propose a stimulated amplified Faraday anomalous dispersion optical filter (SAFADOF) at cesium 1470 nm. The SAFADOF is able to significantly amplify very weak laser signals and reject noise in order to obtain clean signals in strong background. We show that for a weak signal of 50 pW, the gain factor can be larger than 25000 (44 dB) within a bandwidth as narrow as 13 MHz. Having the ability to amplify weak signals with low background contribution, the SAFADOF finds outstanding potential applications in weak signal detections.

“…The direct detection of absorption of 421 nm on  5S 6P 1 2 1 2 transition requires heating a Rb vapor cell up to 80°C-100°C [14,17] and using a photodiode with blue enhanced sensitivity. The spectroscopy at 421 nm can also be carried out using double-resonance spectroscopy [18][19][20][21][22][23], which does not require heating of the Rb vapor cell.…”

In this paper, we present the spectroscopy of the 6P 1/2 state in 87 Rb using a double-resonance technique at 780 nm and 421 nm. The double-resonance technique is implemented using electromagnetically induced transparency (EIT) and optical pumping methods. Using these spectroscopy methods, we have measured the hyperfine splitting of the 6P 1/2 state with precision of <400 kHz, which agrees well with other spectroscopy methods such as electrical discharge and saturated absorption spectroscopy at 421 nm.

“…Laser spectroscopy employing miniaturized vapor cells is attracting growing attention, primarily for its potential applications in compact frequency standards [1][2][3], laser cooling [4][5][6][7], magnetometry [8][9][10] and optical isolation [11], to name a few. In order to obtain a highly resolved spectral lines in the transition from one excited state to another, various optical pumping methods, such as the optical-optical double resonance (OODR) technique, have been successfully used [12].…”

Fluorescence double resonance optical pumping spectrum and its application for frequency stabilization in millimeter scale vapor cells

In recent years, we are observing substantial efforts towards the miniaturization of atomic cells to a millimeter scale and below, with the ultimate goal of enabling efficient and compact light vapor interactions. However, such miniaturization results in a reduction in optical path, effectively reducing the contrast of the optical signal. In order to overcome this obstacle, we have introduced and demonstrated a new approach of fluorescence double resonance optical pumping (FDROP) in the ladder-type atomic system. We have developed a theoretical model to predict the FDROP spectrum and validated this model using experimental results in a millimeter-size cell. We show that the contrast of fluorescence signal of the FDROP approach is higher than the transmission signal in the double resonance optical pumping approach. Taking advantage of this desired property, we have used the FDROP for the purpose of stabilizing the frequency of a laser operating at the telecom waveband with the hyperfine structure of the 5P 3/2 -4D 5/2 transition in a millimeter-size cell. By beating the stabilized laser to another stabilized laser, we obtained frequency instability floor of 9×10 −10 at around 1000 s in terms of Allan deviation. Such sources which are stabilized to miniaturized cells may play an important building block in diverse fields ranging e.g. from communication to metrology.
