An ultra-bright atom laser

Effects of Atom-Laser Interaction on Ultra-Cold Atoms

Radiative reaction in ultra-intense laser–atom interaction

The influence of the radiation of an initially bound electron in an ultra-intense laser field on its dynamics and the consequent corrections to its spectral response are investigated within the relativistic classical Lorentz–Dirac approach. We find appreciable damping of the electron motion in the direction of polarization of the laser field, and a consequent reduction of the electron oscillati...

Note: a transient absorption spectrometer using an ultra bright laser-driven light source.

An apparatus to measure transient absorption spectra for short-lived species in the gas phase was built. This was achieved by coupling a laser-driven plasma light source to a time-gated intensified-CCD spectrometer. Although the laser-driven light source features high brightness, ultra broad bandwidth and long lifetime, we found it possesses a plasma oscillation at a frequency of ~200 kHz with ...

Improvement by laser quenching of an “atom diode”: a one-way barrier for ultra-cold atoms

Different laser devices working as “atom diodes” or “one-way barriers” for ultra-cold atoms have been proposed recently. They transmit ground state level atoms coming from one side, say from the left, but reflect them when they come from the other side. We combine a previous model, consisting of the stimulated Raman adiabatic passage (STIRAP) from the ground to an excited state and a state-sele...

Optics with an atom laser beam.

We report on the atom optical manipulation of an atom laser beam. Reflection, focusing, and its storage in a resonator are demonstrated. Precise and versatile mechanical control over an atom laser beam propagating in an inhomogeneous magnetic field is achieved by optically inducing spin flips between atomic ground states with different magnetic moment. The magnetic force acting on the atoms can...
