“…Based on similar physics and technologies, lasers frequency-stabilized to molecular lines have demonstrated remarkable performances with instability levels in the 10 -14 and 10 -15 range at 1 s and 10 4 s respectively [28][29]. These results have induced great success for the production of compact optical frequency standards, including their recent deployment in space missions [30], optical communications [31], multi-wavelength laser interferometry [32], portable length standards [33] and compact fiber frequency synthesizers [34].…”

Dual-frequency sub-Doppler spectroscopy: Extended theoretical model and microcell-based experiments

Doppler-free spectroscopy using two counter-propagating dual-frequency laser beams in alkali vapor cells has been demonstrated recently, providing the detection of high-contrast sign-reversed natural-linewidth sub-Doppler resonances. However, to date, only a qualitative theory based on a simplified Λ-scheme model has been reported to explain underlying physics of this phenomenon. In this work, we develop a general and extended theoretical model of dual-frequency sub-Doppler spectroscopy (DF SDS) for Cs D 1 line. The latter considers the real atomic energy structure, main relaxation processes and various nonlinear effects including optical pumping, optical transition saturation, Zeeman and hyperfine coherent population trapping (CPT) states. This model allows to describe quantitatively the respective contributions of involved physical processes and consequently to estimate main properties (height and linewidth) of detected sub-Doppler resonances. Experimental results performed with a Cs vapor micro-fabricated cell are reported and explained by theoretical predictions. Spatial oscillations of the sub-Doppler resonance amplitude with translation of the reflection mirror are highlighted. Reported results show that DF SDS could be a promising approach for the development of a fully-miniaturized and high-performance optical frequency reference, with applications in various compact quantum devices.

“…Generating narrow linewidth laser sources in the visible spectrum is a common objective, particularly in the field of atomic and molecular spectroscopy. In this work we focus attention on low-noise light generation at 555.8 nm needed for laser cooling of ytterbium, though the scheme can be employed for wavelengths nearby; for example, those used in an iodine frequency reference [1][2][3] or in confocal laser scanning microscopy [4]. Laser cooling of ytterbium is becoming more prevalent as the range of atomic studies and applications increase.…”

Spectroscopy and laser cooling on the $${}^{1}S_{0}$$ 1 S 0 – $$\,^{3}P_{1}$$ 3 P 1 line in Yb via an injection-locked diode laser at 1,111.6 nm

We generate 555.8 nm light with sub-MHz linewidth through the use of laser injectionlocking of a semiconductor diode at 1111.6 nm, followed by frequency doubling in a resonant cavity. The integrity of the injection lock is investigated by studying an offset-beat signal between slave and master lasers, by performing spectroscopy on the (6s) 2 1 S 0 − (6s6p) 3 P 1 transition in magneto-optically trapped ytterbium, and by demonstrating additional laser cooling of 171 Yb with the 555.8 nm light. For the 1 S 0 − 3 P 1 spectroscopy, we confirm the linear dependence between ground state linewidth and the intensity of an off-resonant laser, namely, that used to cool Yb atoms in a 1 S 0 − 1 P 1 magneto-optical trap. Our results demonstrate the suitability of injection locked 1100-1130 nm laser diodes as a source for sub-MHz linewidth radiation in the yellow-green spectrum.

“…The detailed information of this blue ECDL design was found in Ref. 11. And its spectra as a function of applied current and diode temperature was recorded and analyzed by Chen et al 27 The wavelength tuning can be performed by applying external voltage to a piezoelectric transducer (PZT) (Thorlabs TLK‐PZT1) attached on the grating.…”

“…To directly lock the laser frequency of blue and green lasers on atomic and molecular transitions is better. Molecular iodine (I 2 ) 9,11,12 and tellurium (Te 2 ) have a dense grid of lines spread over a wide range of visible region. The iodine molecular hyperfine spectrum serves as a reference from 500 nm to about 900 nm whereas the absorption spectrum of tellurium molecule spans from 415 to 540 nm.…”

A robust and compact blue optical frequency reference within blue region was designed. A 40-mW telluriumstabilized single-frequency blue diode laser in external cavity was designed with an absorption spectroscopy method based on tellurium molecular transitions. Furthermore, the uncertainty of the frequency stabilization can be pushed to 2 Â 10 À9 at a 10-s integration time. In addition, the correspondence frequency instability was 1.3 MHz when the laser wavelength was 445.75 nm. This study indicates that high-stability frequency reference within the blue region can be achieved with an external cavity diode laser as opposed to the diode-pumped frequency-doubled solid-state laser.
