Three-dimensional atom localization by laser fields in a four-level tripod system
Vladimir S. Ivanov, Yuri V. Rozhdestvensky, Kalle-Antti Suominen
We present a scheme of the high-precise three-dimensional (3D) localization by the measurement of the atomic-level population. The scheme is applied to a four-level tripod-type ato…
Multistate APLIP and VibLIP: From molecular bond extension to atomic transport
Kalle-Antti Suominen
APLIP is a method for using a STIRAP-like three-state configuration with two laser pulses for continuous extension of a molecular bond, introduced in 1998. It is based on time-depe…
Momentum distribution of atoms in one-dimensional Raman cooling with arbitrary coherent population transfer
Vladimir S. Ivanov, Kalle-Antti Suominen
We derive an exact and analytical form for the cold-atom momentum distribution after a large number of one-dimensional (1D) Raman cooling cycles has been applied. Our result shows…
Robust two-dimensional subrecoil Raman cooling by adiabatic transfer in a tripod atomic system
Vladimir S. Ivanov, Yuri V. Rozhdestvensky, Kalle-Antti Suominen
We demonstrate two-dimensional robust Raman cooling in a four-level tripod system, in which velocity-selective population transfer is achieved by a STIRAP pulse. In contrast to bas…
Theory of robust subrecoil cooling by STIRAP
Vladimir S. Ivanov, Yuri V. Rozhdestvensky, Kalle-Antti Suominen
We demonstrate one-dimensional robust Raman cooling in a three-level -type atom, where the velocity-selective transfer is carried out by a STIRAP pulse. In contrast to the stand…
Efficient Two-dimensional Subrecoil Raman Cooling of Atoms in a Tripod Configuration
Vladimir S. Ivanov, Yuri V. Rozhdestvensky, Kalle-Antti Suominen
We present an efficient method for subrecoil cooling of neutral atoms by applying Raman cooling in 2D to a four-level tripod-system. The atoms can be cooled simultaneously in two d…
