WebSep 15, 2007 · Abstract. We have studied double-resonance optical pumping (DROP) as a function of the polarization combination of lasers, laser power, and the alignment of lasers in the 5S {sub 1/2}-5P {sub 3/2}-D {sub 3/2,5/2} ladder-type system of {sup 87}Rb atoms. By considering the two-photon transition probability and optical pumping effects, the … WebOptical pumping is important to a wide variety of applications from the laser, to precise measurements of atomic hyperfine level splittings and atomic clocks, sensitive …
WebDec 22, 2024 · We discuss the interplay between high-contrast Rydberg-state electromagnetically induced transparency (EIT) and optical pumping (OP) in a thermal 87 Rb medium. By pumping the population to one single hyperfine state, we can enhance the interaction strength and, in principle, amplify the EIT peak. WebOptical Pumping. Optical pumping is a process in which light is used to raise (or ‘pump’) electrons from a lower energy level in an atom or molecule to a higher one. From: Lasers for Medical Applications, 2013.
