“…Alkali vapors in paraffin-coated cells were introduced in 1958 [2] and have since been widely applied in atomic physics spanning applications from magnetometers [3,4,5], over slow light studies [6], to spin-squeezing [7], and light-induced atomic desorption (LIAD) [8,9] studies.…”

“…• C. The coating process is similar to the one reported in [8,9]. Our current choice of coating material is a commercial paraffin, Paraflint H 1 , from Sasol Wax American Inc. After baking the system, the break-seal of the paraffin reservoir is broken by a piece of iron sealed in a glass bead ("hammer") manipulated from the outside by a permanent magnet.…”

We have manufactured more than 250 nominally identical paraffin-coated Cs vapor cells (30 mm diameter bulbs) for multi-channel atomic magnetometer applications. We describe our dedicated cell characterization apparatus. For each cell we have determined the intrinsic longitudinal, Γ 01 , and transverse, Γ 02 , relaxation rates. Our best cell shows Γ 01 /2π ≈ 0.5 Hz, and Γ 02 /2π ≈ 2 Hz. We find a strong correlation of both relaxation rates which we explain in terms of reservoir and spin exchange relaxation. For each cell we have determined the optimal combination of rf and laser powers which yield the highest sensitivity to magnetic field changes. Out of all produced cells, 90% are found to have magnetometric sensitivities in the range of 9 to 30 fT/ √ Hz. Noise analysis shows that the magnetometers operated with such cells have a sensitivity close to the fundamental photon shot noise limit.

“…Moreover, the exponential decay in the low-desorption regime was clearly observed in PDMS with Na [2] and K [57] even with violet desorbing light. On the contrary, no evidence of the change of desorption regime is found instead in paraffin in the case of Na, even with more than 1 W of 514 nm radiation [21].…”

Low Energy Atomic Photodesorption from Organic Coatings

et al. 2016

Organic coatings have been widely used in atomic physics during the last 50 years because of their mechanical properties, allowing preservation of atomic spins after collisions. Nevertheless, this did not produce detailed insight into the characteristics of the coatings and their dynamical interaction with atomic vapors. This has changed since the 1990s, when their adsorption and desorption properties triggered a renewed interest in organic coatings. In particular, a novel class of phenomena produced by non-destructive light-induced desorption of atoms embedded in the coating surface was observed and later applied in different fields. Nowadays, low energy non-resonant atomic photodesorption from organic coatings can be considered an almost standard technique whenever large densities of atomic vapors or fast modulation of their concentration are required. In this paper, we review the steps that led to this widespread diffusion, from the preliminary observations to some of the most recent applications in fundamental and applied physics.
