Collisional cross sections and broadening constants are presented for each of the fine-structure components of the second resonance transition in caesium (6S 1 2/-7P 3 2,1/2/, 4555 AA, 4593 AA) perturbed by the five noble gases He-Xe. The results were obtained at perturber pressures of less than 0.5 Torr using the photon echo technique. The cross sections correspond closely with those obtained from spectral line profile measurements, but there are some significant discrepancies.

We report on the characterization of sub-Doppler resonances detected by probing the 6S $_{1/2}$ -7P $_{1/2}$ transition of Cs atom at 459 nm in a microfabricated vapor cell. The dependence of the sub-Doppler resonance (linewidth, amplitude) on some key experimental parameters, including the laser intensity and the cell temperature, is investigated. These narrow atomic resonances are of interest for high-resolution spectroscopy, instrumentation, and may constitute the basis of a near-UV microcell optical standard.We report on the characterization of sub-Doppler resonances detected by probing the 6S$_{1/2}$-7P$_{1/2}$ transition of Cs atom at 459 nm in a microfabricated vapor cell.
