Intensity nonlinearity of the error-signal frequency shift in the modulation spectroscopy of dark resonances and approaches to its reduction
E. A. Tsygankov, S. V. Petropavlovsky, M. I. Vaskovskaya +5
We have found that the error-signal frequency corresponding to the coherent population trapping resonance can be displaced from that of "" transition unperturbed by the optica…

Observation of Nonspreading Wave Packets in an Imaginary Potential
R. Stuetzle, M. C. Goebel, T. Hoerner +8
We propose and experimentally demonstrate a method to prepare a nonspreading atomic wave packet. Our technique relies on a spatially modulated absorption constantly chiseling away…
