Abstract
Ultracold 87Rb atoms were transferred from a QUIC (quadrupole and Ioffe configuration) magnetic trap into a far off resonance optical trap (FORT). FORTs were created by focusing a 150 mW laser beam having a wavelength of 852 nm to a spot having a radius of 20 and 30 µm. A probe laser then passed through the ultracold atom cloud after the magnetic trap was turned off to study the temporal evolution of the optically trapped atoms. Nearly 106 atoms could be transferred into the FORT at temperatures as low as 1 µK with an efficiency as high as 50%. PACS No.: 32.80.Pj
