|Title:||Rapid Production of ^87^Rb BECs in a Combined Magnetic and Optical Potential|
|Published:||August 31, 2009|
|Abstract:||We describe an apparatus for quickly and simply producing ^87^Rb Bose-Einstein condensates. It is based on a magnetic quadrupole trap and a red detuned optical dipole trap. We collect atoms in a magneto-optical trap (MOT) and then capture the atom in a magnetic quadrupole trap and force rf evaporation. We then transfer the resulting cold, dense cloud into a spatially mode-matched optical dipole trap by lowering the quadrupole field gradient to below gravity. This technique combines the efficient capture of atoms from a MOT into a magnetic trap with the rapid evaporation of optical dipole traps; the approach is insensitive to the peak quadrupole gradient and the precise trapping beam waist. Our system reliably produces a condensate with N ~ 2 × 10^6^ atoms every 16 seconds.|
