Mirror magneto-optical trap using circularly polarized light-emitting optical fibers

Masaharu Hyodo, Kazuyuki Nakayama, R. Ohmukai +2 more

A fiber-optic mirror magneto-optical trap (mirror-MOT) that uses a pair of circularly polarized light-emitting optical fibers as an optical access is demonstrated. The fiber is fabricated so that a length of birefringence fiber, designed to be a quarter wave retarder at both wavelengths of 780 and 852 nm, is attached directly onto a polarization-maintaining normal fiber. The polarization states of light emitted from the fibers are sufficiently circular for the operation of a mirror-MOT with 87Rb atoms. The mirror-MOT is able to capture approximately the same number of atoms obtainable with a conventional mirror-MOT. The technique makes it possible to fabricate a compact MOT apparatus by introducing the optical fibers directly into an ultrahigh-vacuum chamber.

Realization of a magneto-optical trap by using linearly-polarized cooling beams

Hoon Yu, Mi Hyun Choi, Jung Bog Kim

We realized two species of magneto-optical traps (MOTs) by using linearly-polarized cooling beams. A mirror MOT was realized by using pairs of σ-π polarized cooling beams. Since the linearly-polarized field could act as opposite circular polarizations, atoms could be loaded on the mirror MOT with the elimination of one quarter-wave plate (QWP) among the four QWPs. However, for a typical MOT, counter-propagating cooling beams had to have opposite circular polarizations. The number of trapped atoms depended strongly on the polarization and optical alignment of the cooling beams when linear polarization with the elimination of one QWP was used. By using this anomalous alignment, we could increase the fluorescence of the mirror MOT. Furthermore, we were also able to realize a six-beam MOT with a configuration of pairs of orthogonal linearly-polarized cooling beams. The direction of the polarization depended strongly on the magnetic field for trapping.

Single-beam atom trap in a pyramidal and conical hollow mirror

K. I. Lee, Jiho Kim, Heung‐Ryoul Noh +1 more

We present a novel and simple magneto-optical trap in pyramidal and in conical hollow mirrors, using a single beam. A diode laser having modulation sidebands at microwaves is used for cooling, trapping, and repumping of rubidium atoms in a vapor cell. When the laser is circularly polarized and sent into the hollow region, three pairs of counterpropagating beams are automatically produced therein that have the same polarization configuration as that of a conventional six-beam magneto-optical trap. The fluorescence by the trapped atoms and its mirror image are observed simultaneously. This system may be useful for atom-manipulation applications such as gravitational atom traps and atom waveguides.
