Rydberg spectroscopy of a Rb MOT in the presence of applied or ion created electric fields

摘要: Rydberg spectroscopy of rubidium cold atoms trapped in a magneto-optical trap (MOT) was performed quartz cell. When electric fields acting on the generated by plate external to cell were continuously applied, charges walls created, as monitored spectra. Avoiding accumulation and realizing good control over applied field instead obtained when only for short time, typically few microseconds. In two-photon excitation via 62P state state, laser resonant with 52S–62P transition photoionizes excited state. The photoionization-created ions produce an internal which deforms spectra, Autler-Townes absorption
