Continuous loading and transport of strontium atoms in a ring cavity

ORAL

Abstract

We will present continuous loading of cold $^{88}$Sr atoms into a ring cavity in the strong collective atom-cavity coupling regime. Our approach is to guide atoms through a series of spatially separated laser cooling and deceleration stages before using a 3D molasses to capture them into a magic-wavelength conveyor belt-style moving optical lattice supported by the ring cavity. Our continuous, high flux apparatus is an excellent starting point for a continuous wave superradiant laser [1], dead-time free atom interferometers [2], and high-precision atomic clocks [3].
