Cesium alignment produced by pumping with unpolarized light

Shi, Yongqi ; Weis, Antoine

In: The European Physical Journal D, 2018, vol. 72, no. 4, p. 73

We demonstrate optical pumping on the four hyperfine components of the Cs D1 transition by unpolarized (UPL) resonant laser light. The evidence is based on the reduction of the absorption coefficients κ0 with increasing light power P in an uncoated Cs vapor cell with isotropic spin relaxation. For comparison we perform the same quantitative κ0(P) measurements with linearly-polarized light...
