Abstract

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.

) 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.

Electrodeless-discharge-vapor-lamp-based Faraday anomalous-dispersion optical filter

We report an excited-state Faraday anomalous-dispersion optical filter operating on the rubidium 5P(3/2)-5D(5/2) transition (775.9 nm in vacuum) without the use of a pump laser. An electrodeless discharge vapor lamp is employed to replace the Rb vapor cell in a traditional Faraday anomalous-dispersion optical filter system. Atoms can be excited by power rather than a complex frequency-locked pump laser. A proof-of-concept experimental demonstration with a maximum transmission of 1.9% and a filter bandwidth of 650 MHz is presented.

Electrodeless-discharge-vapor-lamp-based optical atomic filter

Qinqing Sun, Yelong Hong, Xiaobo Xue +4 more

An excited-state Faraday anomalous dispersion optical filter (FADOF) has been demonstrated, which utilizes a rubidium electrodeless-discharge-vapor-lamp rather than an external pump laser. When the lamp is turned off, the lamp-based filter can be treated as a ground-state FADOF. The compact lamp based FADOF holds promise for realing a frequency-fixed diode laser systems (such as a 1529 nm laser for optical communication application) and a multi-frequency filters.

A Power Efficient Faraday Laser at 780nm Rb Transition

Zhihong Gao, Jingbiao Chen

Summarywe report on the development of a power efficient Faraday laser working at 780nm Rb transition using an atomic vapor Faraday filter as a frequency-selecting element. In the routine linear-cavity of Faraday laser, a partial reflectivity cavity mirror was used as output coupler. In this work, a high-reflection mirror (R>99.98%) replaces the partial reflectivity cavity mirror, the transmitted light of the Faraday optical filter is fully used as feedback beam and for frequency selection, while the light with polarization perpendicular to the transmitted part from the second polarizing beam splitter (PBS2) of Faraday anomalous dispersion optical filter (FADOF) is output. Single frequency laser is obtained at 780 nm Rb transition over a range of laser diode (LD) current from 60 to 140 mA. Such a single-frequency laser will be an excellent optical frequency standard by frequency stabilization technique.

Diode laser operating on an atomic transition limited by an isotope ^87Rb Faraday filter at 780 nm

Zhiming Tao, Yelong Hong, Bin Luo +2 more

We demonstrate an extended cavity Faraday laser system using an antireflection-coated laser diode as the gain medium and the isotope (87)Rb Faraday anomalous dispersion optical filter (FADOF) as the frequency selective device. Using this method, the laser wavelength works stably at the highest transmission peak of the isotope (87)Rb FADOF over the laser diode current from 55 to 140 mA and the temperature from 15°C to 35°C. Neither the current nor the temperature of the laser diode has significant influence on the output frequency. Compared with previous extended cavity laser systems operating at frequencies irrelevant to spectacular atomic transition lines, the laser system realized here provides a stable laser source with the frequency operating on atomic transitions for many practical applications.
