摘要
We have developed a simple method for the fast and efficient production of a Bose-Einstein condensate (BEC) on an atom chip. By using a standard six-beam magneto-optical trap and light-induced atom desorption for loading, 3x10(7) Rb-87 atoms are collected within 1 s and loaded into a small-volume magnetic potential of the chip with high efficiency. With this method, a BEC of 3x10(3) atoms is realized within a total time of 3 s. We can realize a condensate of up to 2x10(4) atoms by reducing three-body collisions. The present system can be used as a fast and high-flux coherent matter-wave source for an atom interferometer.
