“…While the increased signal strength of the cycling resonance is the most striking attribute of the POLEAS method, there are other appealing aspects that could prove equally beneficial. The simplicity of the experimental configuration and the fact that the Doppler background is automatically removed without the need for a separate beam (as in D-F SAS), mean that POLEAS can readily be implemented in a compact package [22]. Furthermore, by enhancing the cycling transition signal and simultaneously reducing the other nearby spectral features, an auto-locking laser stabilization scheme becomes easier to accomplish, especially compared with D-F SAS, where the crossover peaks provide the strongest features.…”

We demonstrate a variation of pump-probe spectroscopy that is particularly useful for laser frequency stabilization. The polarization-enhanced absorption spectroscopy (POLEAS) signal provides a significant improvement in signal-to-noise ratio over saturated absorption spectroscopy (SAS) for the important and commonly used atomic cycling transitions. The improvements can directly increase the short-term stability of a laser frequency lock, given sufficient servo loop bandwidth. The long-term stability of the POLEAS method, which is limited by environmental sensitivities, is comparable to that of SAS. The POLEAS signal is automatically Doppler-free, without requiring a separate Doppler subtraction beam, and lends itself to straightforward compact packaging. Finally, by increasing the amplitude of the desired (cycling) peak, while reducing the amplitude of all other peaks in the manifold, the POLEAS method eases the implementation of laser auto-locking schemes.

“…Typically, a weak linearly polarized probe beam is superimposed on a circularly polarized counter-propagating pump beam in a gas or vapor cell. [26][27][28][29] The observed signal is derived from the change in the polarization of the probe laser beam after it traverses the gas. This change is due to the optical anisotropy induced by the stronger pump beam, which arises from optical pumping that redistributes the population of the magnetic sublevels.…”

We describe a spectroscopy experiment, suitable for upper-division laboratory courses, that investigates saturated absorption spectroscopy and polarization spectroscopy in a neon discharge. Both experiments use nearly identical components, allowing students to explore both techniques in a single apparatus. Furthermore, because the wavelength of the laser is in the visible part of the spectrum (640 nm), the experiment is well-suited for students with limited experience in optical alignment. The labs nicely complement a course in atomic or plasma physics, provide students with the opportunity to gain important technical skills in the area of optics and lasers, and can provide an introduction to radio-frequency electronics.

“…Some compact [4] or miniaturized setups [5][6][7] have been proposed to stabilize a laser source frequency using SA resonances. Inspired by the work of Villalba et al [8], who observed SA resonances on an atomic vapor probed by diffuse light, we consider in this work the possibility of using diffuse light in a SA setup and we identify some advantages for its miniaturization.…”
