    • Actually the tightly confining beam is already on with ∼0.7 W during the very far-detuned molasses phase. Such a power corresponds to a light shift similar to that created by the wide beam and the additional trapping volume permits a gain of ∼10% in the atom number.

    • An experimental proof of the role of three-body collisions is the fact that using more power (14 W rather than 6 W) in the confining beam leads to a lower atom number.

    • For background losses, the formula is γ=η-4-R (η-3). The difference comes from the fact that three-body losses mostly affect the atoms at the trap center where the density is higher.

    • To further simplify the degenerated gas apparatus, all the laser beams for trapping and for cooling could be generated from a single 1560 nm fibered diode after amplification and frequency doubling.
