“…This result is better than that in [8] (the authors have achieved a frequency stability of 3 × 10 −8 ) and comparable to the one reported by Di Fancesco et al [14] (frequency stability: 5 × 10 −10 but obtained with a specially prepared micro-fabricated gas cell). The frequency reproducibility measurement was unworkable using the matrix method [15,16] because the counter meter bandwidth (1 GHz) was too narrow while the maximum difference between rubidium absorption peaks is under 6 GHz.…”

“…The SSFLC cell is a modulator itself and described in [7]. In [8,9] one of the co-authors used the SSFLC cell practically as a laser-mode polarization switch for the frequency stabilization of the Zeeman He-Ne laser and the level of 3 × 10 −8 was achieved. However, in the offered setup we adapt SSFLC cell properties to weak DAVLL optical signals with a full self-designed synchronous detection module based on a microprocessor system.…”

We present a concept of the polarization switching detection method implemented for frequency-stabilized lasers, called the polarization switching dichroic atomic vapor laser lock (PSDAVLL) technique. It is a combination of the well-known dichroic atomic vapor laser lock method for laser frequency stabilization with a synchronous detection system based on the surface-stabilized ferroelectric liquid crystal (SSFLC).The SSFLC is a polarization switch and quarter wave-plate component. This technique provides a 9.6 dB better dynamic range ratio (DNR) than the well-known two-photodiode detection configuration known as the balanced polarimeter. This paper describes the proposed method used practically in the VCSEL laser frequency stabilization system. The applied PSDAVLL method has allowed us to obtain a frequency stability of 2.7×10⁻⁹ and a reproducibility of 1.2×10⁻⁸, with a DNR of detected signals of around 81 dB. It has been shown that PSDAVLL might be successfully used as a method for spectra-stable laser sources.

B Kharkov, UkraineFerroelectric liquid crystals (FLC) as light modulators in the stabilization system of a Zeeman laser increase the quality of stabilization due to the high switching speed and make the whole system very compact. We analyze the operation of the optical part of such a stabilization system and derive optimum values of the FLC cell parameters. Properties of available liquid crystals and their temperature dependence are considered as well as, in particular, the intluence of a slight ellipticity of the laser radiation.
