Abstract

Optical-optical double-resonance (OODR) Spectra for the 52P1/2−62S1/2and the 52P3/2−42D3/2,5/2transition of87Rb have been used for frequency stabilization in near-infrared region for many years. Though the method works well, it calls for locked 780nm lasers to pump Rb atoms into 52P3/2. We are trying to use an electrodeless discharge Rb vapor lamp to replace the complex locked pumping laser. The lamp's spectra show us that there are two spectral signals, 780nm and 795nm, are much larger than others. We are trying to make 52P3/2level populated by shining the lamp light into a Rb vapor cell. Meantime, the lamp could absorb 1529 nm laser most seriously when operating in red mode. The absorption signal with high SNR but with several hundred megahertz line-width is hopefully to be used to lock the 1529 nm laser directly without 780 nm laser. The advantage of the lamp used in the frequency stabilized system is to reduce the size and cost of 1.5 μm wavelength standard for optical communication application.

Laser 728 nm Spectroscopy of Electrodeless Discharge Rb Lamp

Zhongzheng Liu, Xiaobo Xue, Fuzeng Niu +3 more

We mainly report the 728.0 nm transition between 7S 1/2 and 5P 1/2 laser spectroscopy of an electrodeless discharge Rb vapor lamp, which is the clock transition of a potential four-level active optical clock, once laser cooled and trapped Rb atoms are pumped by 359.2 nm laser. To realize this proposition, we study the linewidth and absorption characteristics of the 728.0 nm laser absorption spectrum of a rubidium electrodeless discharge vapor lamp with varying lamp temperature and rf driving power respectively, measured by an external cavity diode laser in a Littrow configuration. The measured 728.0 nm spectrum of a glass cell filled with Rb and Ar buffer gases in the electrodeless discharge Rb lamp based Faraday filter stabilized laser can be a heterodyne comparison reference for the weak power output of a possible cold Rb four-level active optical clock at 728.0 nm clock transition with laser cooled and trapped atoms. To the best of our knowledge, there has not been any research reported on Rb 728.0 nm laser spectroscopy in detail.

) 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 performance-improved electrodeless discharge lamp-based excited-state Faraday anomalous dispersion optical filter (LESFADOF), we realized a heterogeneously Faraday laser with the frequency corresponding to atomic transition, working stably over a range of laser diode (LD) current from 85 mA to 171 mA and the LD temperature from 11 °C to 32 °C, as well as the 24-hour long-term frequency fluctuation range of no more than 600 MHz. Both the laser linewidth and relative intensity noisy (RIN) are measured. The Faraday laser lasing on Rb 1529 nm transition (telecom C-band) can be applied to further research on metrology, microwave photonics and optical communication systems. Besides, since the transitions correspongding to the populated excited-states of alkali atoms within lamp are extraordinarily rich, this scheme can increase the flexibility for choosing proper wavelengths for Faraday laser and greatly expand the coverage of wavelength corresponding to atomic transmission for laser frequency stabilization.

Demonstration of an excited-state Faraday anomalous dispersion optical filter at 1529 nm by use of an electrodeless discharge rubidium vapor lamp

Qinqing Sun, Yelong Hong, Wei Zhuang +2 more

An excited-state Faraday anomalous dispersion optical filter (ESFADOF) operating on the rubidium 5P3/2-4D5/2 transition (1529.4 nm in vacuum) is demonstrated, which utilizes an electrodeless discharge lamp rather than a laser-pumped Rb vapor cell as in a traditional ESFADOF system. When the lamp operates in the red mode with 3.5 W radio-frequency driving power, a twin-peak line-shaped transmission spectrum is obtained, which has a maximum transmittance of 21.9% (without taking into account the system loss and fluorescence background). ESFADOF by exploiting the 5P3/2-4D3/2 transition (1529.3 nm in vacuum) is also explored. A single-peak transmission spectrum with a maximum transmittance of about 3% is achieved. The electrodeless discharge lamp based ESFADOF holds promise for realizing a compact, low-cost, and good long-term frequency-stabilized laser system for optical communication applications.

Faraday laser at Rb 1529 nm transition for optical communication systems

We experimentally demonstrate a Faraday laser at Rb 1529 nm transition by using a performance-improved Rb electrodeless-discharge-lamp-based excited-state Faraday anomalous dispersion optical filter as the frequency-selective element. Neither the electrical locking scheme nor the additional frequency-stabilized pump laser are used. The frequency of the external-cavity diode laser is stabilized to the Rb 1529 nm transition, and the Allan deviation of the Faraday laser is measured by converting the optical intensity into frequency. The Faraday laser can be used as a frequency standard in the telecom C band for further research on metrology, microwave photonics, and optical communication systems.

The population ratio between the excited states of rubidium in the electrodeless discharge rubidium vapour lamp is calculated according to the near-infrared spectra in the region of 780–1550 nm. By using a 1529 nm laser, we measure the density of natural rubidium atoms at the 5P 3/2 level. The populations of different excited states are then clarified.

We demonstrate the spectra of 87Rb 5S1/2-5P3/2-4D3/2(4D5/2) 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,shows a much better signal-to-noise ratio(SNR) and narrower linewidth.When frequency of 1 529 nm external-cavity diode laser is stabilized to the DROP spectrum of 87Rb 5P3/2(F′=3)-4D3/2(F″=3) transition,the preliminary result of residual frequency jitter after being locked is～0.65 MHz within 300 s.This result is clearly much better than that in case of frequency stabilized by using OODR scheme(～1.8 MHz within 300 s).
