We show that coherence times of ~ 100 ns are achievable with coherent Rydberg atom spectroscopy in micrometre-sized thermal vapour cells making them robust and promising candidates for scalable quantum devices like single-photon sources.

Ionisation of excited caesium atoms (9.4⩽n*⩽ or ≈29) in collisions with Cs(6S)

Vitas Švedas

The ionisation yields of the optically excited caesium atoms (9.4<or=n*<or approximately=29) are measured in a vapour cell at a caesium vapour density of about 10 14 cm -3 . Direct ionisation rate constants are given for Rydberg atoms with 9.4<or=n*<or=21.4. Collisions with caesium ground-state atoms and black-body radiation strongly modify the population of Rydberg levels with n*>or approximately=25 so the concept of direct collisional ionisation cannot be applied to those levels. The diffusional ionisation mechanism of Rydberg atoms in vapour cells, atomic beams or buffer gases is discussed.The ionisation yields of the optically excited caesium atoms (9.4<or=n*<or approximately=29) are measured in a vapour cell at a caesium vapour density of about 10 14 cm -3 .
