Phase Stabilized Arbitrary Lattices with Magnetic Levitation in Time-of-Flight
POSTER
Abstract
We present three portions of our apparatus that enable ~60 ms time-of-flight images to be taken of atoms released from arbitrary lattices. First, we present the generation of these optical lattices using a pair of Acousto-Optic Modulators [AOM]. Second, the phase-stabilization of these lattices using an in-house manufactured interferometer and piezo-actuated mirror. Third, a magnetic levitation system for ${}^{87}$Rb using supercapacitors and a MOSFET-based switched circuit that enables 10's of ms time-of-flight while staying in focus with a high-resolution imaging system.
