Demonstration and characterization of a detector for minimally destructive detection of Bose condensed atoms in real time

Figl, C; Longchambon, L; Jeppesen, M; Kruger, M; Bachor, Hans; Robins, N. P; Close, J. D


We present the first detector capable of recording high-bandwidth real time atom number density measurements of a Bose Einstein condensate. Based on a two-color Mach-Zehnder interferometer, our detector has a response time that is six orders of magnitude faster than current detectors based on CCD cameras while still operating at the shot-noise limit. With this minimally destructive system it may be possible to implement feedback to stabilize a Bose-Einstein condensate or an atom laser.
