Bose-Einstein Condensation in a crossed optical dipole trap:  Absorption images of atomic cloud after evaporation in the crossed dipole trap after a non-linear evaporation ramping. (a) Thermal cloud before BEC transition after an evaporation ramp of 200 msecs to a final power of 3.5 W in each of the trapping beams (b) After evaporative ramp of 400 msecs to a final power of 2.4 W (c) Bose-Einstein condensate after evaporative cooling for 600 msecs to a final power of 1.5 W. Field of view is 300 microns (Jan, 2007)
