All-optical production of L7i Bose-Einstein condensation using Feshbach resonances

Noam Gross, Lev Khaykovich

We show an all-optical method of making $^{7}\text{L}\text{i}$ condensates using the tunability of the scattering length in the proximity of a Feshbach resonance. We report the observation of two Feshbach resonances on the $|F=1,{m}_{F}=0⟩$ state. A narrow (broad) resonance of 7 G (34 G) width is detected at $831\ifmmode\pm\else\textpm\fi{}4\text{ }\text{G}$ $({884}_{\ensuremath{-}13}^{+4}\text{ }\text{G})$. The position of the scattering length zero crossing between the resonances is found at $836\ifmmode\pm\else\textpm\fi{}4\text{ }\text{G}$. The broad resonance is shown to be favorable for runaway evaporation which we perform in a crossed-beam optical-dipole trap. Starting directly from the phase-space density of a magneto-optical trap we observe a Bose-Einstein condensation threshold in less than 3 s of forced evaporation.We show an all-optical method of making $^{7}\text{L}\text{i}$ condensates using the tunability of the scattering length in the proximity of a Feshbach resonance.
