Dense atom clouds in a holographic atom trap.
We demonstrate the production of high-density cold 87Rb samples (2 x 10(14) atoms/cm3) in a simple optical lattice formed with YAG light that is diffracted from a holographic phase plate. A loading protocol is described that results in 10,000 atoms per 10 microm x 10 microm x 100 microm unit cell of the lattice site. Rapid free evaporation leads to a temperature of 50 microK and phase space den...
متن کاملHigh-density mesoscopic atom clouds in a holographic atom trap
We demonstrate the production of micron-sized high-density atom clouds of interest for mesoscopic quantum information processing. We evaporate atoms from 60 !K, 3"1014 atoms/cm3 samples contained in a highly anisotropic optical lattice formed by interfering diffracted beams from a holographic phase plate. After evaporating to 1 !K by lowering the confining potential, in less than a second the a...
متن کاملA New Atom Trap: The Annular Shell Atom Trap (ASAT)
In the course of exploring some aspects of atom guiding in a hollow, optical fiber, a small negative potential energy well was found just in front of the repulsive or guiding barrier. This results from the optical dipole and the van der Waals potentials. The ground state for atoms bound in this negative potential well was determined by numerically solving the Schrödinger eq. and it was found th...
متن کاملAtom lithography with a holographic light mask.
In atom lithography with optical masks, deposition of an atomic beam on a given substrate is controlled by a standing light-wave field. The lateral intensity distribution of the light field is transferred to the substrate with nanometer scale. We have tailored a complex pattern of this intensity distribution through diffraction of a laser beam from a hologram that is stored in a photorefractive...
