We have demonstrated an output coupler for Bose condensed atoms in a magnetic trap. Short pulses of rf radiation were used to create Bose condensates in a superposition of trapped and untrapped hyperfine states. The fraction of out-coupled atoms was adjusted between 0% and 100% by varying the amplitude of the rf radiation. This configuration produces output pulses of coherent atoms and can be regarded as a pulsed {open_quotes}atom laser.{close_quotes} {copyright} {ital 1997} {ital The American…

Nonclassical effect in the MIT output coupler for the Bose–Einstein condensate
Abstract A quantum dynamical theory for output coupler of the trapped Bose–Einstein condensate is presented under no rotating wave approximation (RWA) based on the MIT experiment (Phys. Rev. Lett. 78
Strong Outcoupling from Spin-2 87 Rb Bose Einstein Condensates
A pulsed atom laser is experimentally demonstrated by means of outcoupling coherent atoms from 87Rb Bose–Einstein condensates in magnetic trap via radio-frequency pulses. To study the strong
Probing a Bose-Einstein condensate with an atom laser.
TLDR
The s-wave scattering length is measured that, in low energy collisions, describes the interaction between the |F = 1,m(F) = -1) and|F = 2,m-F = 0) hyperfine ground states in (87)Rb.
Outcoupling from a Bose-Einstein condensate with squeezed light to produce entangled-atom laser beams
We examine the properties of an atom laser produced by outcoupling from a Bose-Einstein condensate with squeezed light. We model the multimode dynamics of the output field and show that a significant
Output coupling of a Bose-Einstein condensate formed in a TOP trap
Two distinct mechanisms are investigated for transferring a pure 87Rb Bose-Einstein condensate in the |F = 2, mF = 2 state into a mixture of condensates in all the mF states within the F = 2
Ramsey interferometry with an atom laser.
TLDR
This system is well suited to testing recent proposals for generating and detecting squeezed atomic states, and the current and the potentially achievable interferometric phase sensitivity are determined.
Scheme for preparation of coherent hybrid atomic–molecular beams
Abstract We study a possible scheme to realize coherent hybrid atomic–molecular beams based on MIT output coupler for Bose–Einstein condensate just by adding a tunable narrow magnetic Feshbach
Observation of Interference Between Two Bose Condensates
TLDR
It is demonstrated that Bose condensed atoms are “laser-like”; that is, they are coherent and show long-range correlations and have direct implications for the atom laser and the Josephson effect for atoms.
Quantum Dynamics of a Raman Atom Laser by Using a Feshbach-Resonance-Tuned Atomic Bose-Einstein Condensate
We study a Raman atom laser output coupler by considering a Feshbach-resonance-tuned atomic Bose-Einstein condensate which is often viewed as a dilute system since the collisions can be tuned.
Properties of a Raman Atom Laser Output Coupler
We have studied the characteristics of an atom laser created by removing atoms from a Bose-Einstein condensate (BEC) via a two-photon Raman process. In contrast with outcoupling by RF transitions,
