“…Since Faraday anomalous dispersion optical filter was introduced in 1956 [30], Faraday optical filters composed of different elements have been developed [31][32][33][34][35][36][37][38][39][40][41][42][43][44]. Faraday optical filters have been used as frequency-selecting element and applied to various applications, including Na guide-star [45], Mollow triplet filtering [46], Faraday geometry [47], Doppler lidar [48] and active optical clock [49].…”

We demonstrate a Faraday laser at Cs-D2 resonance line 852 nm using a Cs Faraday optical filter as frequency-selecting element. In contrast to typical diode laser with high stability of the emission frequency by additional control systems, our Faraday laser offers stable output frequency exactly set by the peak transmission frequency of the Cs 852 nm Faraday optical filter. The system works stably over a range of laser diode (LD) current from 60 to 130 mA and the LD temperature from 14 to 35 • C, as well as the 48-h wavelength fluctuation range of no more than ± 2 p.m. A most probable linewidth of 17 kHz with Lorentz fitting is obtained by beating between two identical laser systems. The wavelength of our system is stabilized within transmission frequency region of 852 nm Faraday optical filter, and the peak of the transmission is corresponding to Cs atomic Doppler broadened line at the cell temperature of 41 • C and the magnetic field of 330 G, making it suitable for laser-pumped Cs gas-cell and atomic beam frequency standard, etc. Moreover, this scheme is firstly used on Cs atom, opening new doors in research of Faraday laser and its applications.

“…Analysis of available literature showed that most publications are either missing complete derivations or are not easily adaptable to different situations, thus limiting their usefulness. For example, Yeh and Van Baak provide only a limited treatment of the quantum mechanical description of atomic states, ignoring the hyperfine structure, while Dressler et al give a detailed solution, but only for weak external magnetic fields, which is unsuitable for our high-field application [12][13][14]. Yin and Shay present a theory valid for arbitrary magnetic field for a cesium Faraday filter operating at the Cs D 2 line, but their letter lacks detail to make it useful for others to replicate [15].…”

Sodium and potassium vapor Faraday filters revisited: theory and applications

et al. 2009

A complete theory describing the transmission of atomic vapor Faraday filters is developed. The dependence of the filter transmission on atomic density and external magnetic field strength, as well as the frequency dependence of transmission, are explained in physical terms. As examples, applications of the computed results to ongoing research to suppress sky background, thus allowing Na lidar operation under sunlit conditions, and to enable measurement of the density of mesospheric oxygen atoms are briefly discussed.

“…A Faraday anomalous dispersion optical filter (FADOF) is an important kind of atomic optical filter with high transmittance, a narrow band, and excellent out-of-band rejection [1][2][3][4][5][6][7]. It is widely used in free-space laser communication [8][9][10], lidar [11][12][13], laser systems [14], and so on.…”

Excited state Faraday anomalous dispersion optical filters based on indirect laser pumping

et al. 2014

View full text Add to dashboard Cite

The direct pump method now used in excited state Faraday anomalous dispersion optical filters (ES-FADOFs) requires that the transition between the target and the ground state is an electric dipole allowed transition and that a laser that operates at the exact pump wavelength is available. This is not always satisfied in practice. An indirect laser pump method for ES-FADOF is proposed and experimentally realized. Compared with the commonly used direct pump method, this indirect pump method can reach the same performance using lasers at very different wavelengths. This method can greatly extend the wavelength range of FADOF and provide a novel scheme for ES-FADOF design.
