A one-dimensional ultracold medium of extreme optical depth

Abstract

We report on the preparation of a one-dimensional ultracold medium in a hollow-core photonic crystal fiber, reaching an effective optical depth of 1000(150). We achieved this extreme optical depth by transferring atoms from a magneto-optical trap into a far-detuned optical dipole trap inside the hollow-core fiber, yielding up to 2.5(3)$\times$10${}^5$ atoms inside the core with a loading efficiency of $2.5(6)\%$. The preparation of an ultracold medium of such huge optical depth paves the way towards new applications in quantum optics and nonlinear optics.
