Two-Pulse Ramsey Spectroscopy: Resources for Niles

[Niles]

Hi

Does anybody know of any good papers/texts explaining this concept? I am mainly looking for two-pulse RS.


Niles.

OK, I found this: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.8.7828&rep=rep1&type=pdf

On page 5 (section 3.3, more specifically), they say that by changing the detuning, they create a Ramsey pattern (i.e., they induce a phase shift between the two pulses). Can someone explain to me why a detuning between atom-laser is the same as a phase shift between the two pulses?

Best.

I didn't read the paper, but did notice that they talk of a pair of pi/2 pulses separated by an evolution period. This sounds like an optical echo experiment, analogous is some ways to NMR spin echoes. Check out some early papers (1980's) by Warren S. Warren. I recall that he studied this phenomenon, and he had a nice way with explaining things.
