Abstract: We have studied the loading of a single-beam or a crossed dipole trap made by a Nd:YAG laser. The loading was performed from a magnetic trap or after a molasses phase with cesium atoms. Looking. for high atomic density to perform a fast evaporation to reach the Bose-Einstein Condensation, we found that a crossed dipole trap with a waist of 30 mu m and a laser power P=10 W, loaded from a molasses, gives a good starting point to begin evaporation with 5 x 10(6) atoms loaded in 50 ms.
