Abstract

We have studied double-resonance optical pumping (DROP) as a function of the polarization combination of lasers, laser power, and the alignment of lasers in the 5S1/2-5P3/2-D3/2,5/2 ladder-type system of Rb87 atoms. By considering the two-photon transition probability and optical pumping effects, the changes in the relative magnitude of the DROP hyperfine structures as a function of the polarization combination of the lasers were analyzed theoretically. The theoretical results are in good agreement with the experimental results. Owing to the low optical pumping effect in the cycling transition, we could see the dependence of the spectrum on the laser power in the 5P3/2-4D5/2 transition distinctly. Also, the spectral linewidths as a function of the alignment between the lasers were measured 12.2 MHz for copropagating beams and 6.9 MHz for counterpropagating beams.

Optical pumping effects in ladder-type electromagnetically induced transparency of 5S1/2–5P3/2–5D3/2transition of87Rb atoms

Han Seb Moon, Heung‐Ryoul Noh

We have investigated the optical pumping effects of single-resonance optical pumping (SROP) and double-resonance optical pumping (DROP) in the ladder-type electromagnetically induced transparency (EIT) of the 5S1/2–5P3/2–5D3/2 transition of 87Rb atoms. In the 5S1/2(F = 2)–5P3/2(F' = 3)–5D3/2(F'' = 2, 3) transition with the single-resonance cycling 5S1/2(F = 2)–5P3/2(F' = 3) transition, we observed the transmittance spectrum due to DROP and EIT. Based on our experimental results investigated according to the laser power (the probe and the coupling) and the coupling laser detuning, we revealed that DROP was significant for the transmittance spectrum. Particularly, in the 5S1/2(F = 2)–5P3/2(F' = 1, 2)–5D3/2(F'' = 1) transition without a cycling transition, we observed the two-photon absorption due to two-photon atomic coherence, when the probe laser power was weak and the coupling laser power was strong.We have investigated the optical pumping effects of single-resonance optical pumping (SROP) and double-resonance optical pumping (DROP) in the ladder-type electromagnetically induced transparency (EIT) of the 5S1/2–5P3/2–5D3/2 transition of 87Rb atoms.

Double resonance optical pumping effects in electromagnetically induced transparency

Han Seb Moon, Lim Lee, Jung Bog Kim

We present the double resonance optical pumping (DROP) effect of ladder-type electromagnetically induced transparency (EIT) in the 5S1/2-5P3/2-5D5/2 transition of 87Rb atoms. When many atoms of the ladder-type atomic system are simultaneously resonant with the two laser fields, the population of one ground state can be optically pumped into another ground state through intermediate states and excited states. In this paper, we reveal that most previous results for the ladder-type EIT include the DROP effect. When the probe laser is very weak and the coupling laser is strong, we can observe the double structure transmittance spectrum, a narrow spectrum due to the EIT and a broad spectrum due to the DROP, in the 5S1/2(F=2)-5P3/2(F'=3)-5D5/2(F"=4) cycling transition.We present the double resonance optical pumping (DROP) effect of ladder-type electromagnetically induced transparency (EIT) in the 5S1/2-5P3/2-5D5/2 transition of 87Rb atoms.

Frequency stabilization of a 13 μm laser diode using double resonance optical pumping in the 5P_3/2-6S_1/2 transition of Rb atoms

Han Seb Moon

The frequency stabilization of a laser diode in the 1.3 microm region using double resonance optical pumping (DROP) spectrum in the 5P(3/2)-6S(1/2) transition of (87)Rb atoms is demonstrated. The signal-to-noise ratio of the DROP spectrum is approximately ten times higher than that of the previous optical-optical double resonance spectrum. The spectral linewidth of the DROP measures 8.4 MHz. When the frequency of a 1.367 microm laser diode is stabilized to the DROP spectrum, the frequency stability is 9 x 10(-12) after 100 s. Also, the wavelength of the frequency-stabilized laser locked to the 5P(3/2)-6S(1/2) transition using a wavelength meter is measured.The frequency stabilization of a laser diode in the 1.3 microm region using double resonance optical pumping (DROP) spectrum in the 5P(3/2)-6S(1/2) transition of (87)Rb atoms is demonstrated.

We demonstrate the spectra of 87Rb 5S1/2 - 5P3/2 - 4D3/2 transitions by utilizing the double-resonance optical-pumping (DROP) and optical-optical double-resonance (OODR) techniques, respectively. The DROP spectrum, compared with the traditional OODR spectrum, show a much better signal-to-noise ratio (SNR). Paying special attention to the influence of alignment of lasers where the coupling and probe beams are counter-propagation and co-propagation on DROP spectrum, so as to further narrow the spectral width by means of electromagnetically induced transparency (EIT). When -the frequency of 1.5μm fiber-pigtailed butterfly-type distributed-feedback (DFB) diode laser is stabilized to the DROP spectrum of 87Rb 5P3/2 - 4D3/2 transition, the preliminary result of residual frequency jitter after stabilization is ~ ±1.3 MHz within 60 s.We demonstrate the spectra of 87Rb 5S1/2 - 5P3/2 - 4D3/2 transitions by utilizing the double-resonance optical-pumping (DROP) and optical-optical double-resonance (OODR) techniques, respectively.
