摘　　要：A simplified two-dimensional(2-D)magneto-optical trap(MOT)for loading atoms into a 3-D MOT is realized.Instead of utilizing multiple wave plates and beam splitters to cover a large cooling region,we deploy cooling beams with elliptical cross-section profiles to achieve a comparable cooling volume.This simplification reduces the cost and difficulty of alignment.The 3-D MOT achieves a loading rate of 2×108 atoms per second via this simplified 2-D MOT.Correlation between the loading rate and parameters of optical system is also determined.
