We report on the precision measurement of aluminum atoms 2 P 1 / 2 − 2 S 1 / 2 transition at 394 nm and 2 P 3 / 2 − 2 S 1 / 2 transition at 396 nm in a hollow-cathode lamp. Both absorption and saturated absorption spectra are measured. From the absorption spectra, the Doppler linewidth is estimated to be 2.65 GHz. The saturated absorption spectra are analyzed based on a velocity-changing collisions model. With a frequency comb calibrated wavemeter, the frequencies of 2 P 1 / 2 ( F ′ = 3 ) − 2 S…

The technique employs polarization spectroscopy, which produces a natural dispersive lineshape whose zero-crossing is largely immune to environmental drifts, making this signal an ideal absolute frequency reference for Yb+ ion trapping experiments and makes the approach attractive for stabilization of laser sources in atomic physics applications.

Abstract.Hollow cathode (HC) lasers usually operate in a single axial mode without any optical selection. This is attributed to the large homogeneous linewidth of the gain curve due to the relatively
