Design and characterization of a laser system for air-borne gravimetry — •Alisa Ukhanova1, Julia Pahl1, Markus Krutzik1,2, and the AeroQGrav team1, 3,4,5,6,7,8,9 — 1Humboldt-Universität zu Berlin, Institut für Physik — 2Ferdinand-Braun-Institut (FBH), Leibniz-Institut für Höchstfrequenztechnik, Berlin — 3LUH, Hannover — 4DLR, Hannover — 5TUB, Braunschweig — 6BKG, Leipzig — 7TUC, Clausthal — 8Geo++ GmbH, Garbsen — 9iMAR Navigation GmbH, Ingbert
The *AeroQGrav* project strives to demonstrate a long-term stable air-born gravimeter, with a higher spatial and temporal resolution and a better long-term stability compared to the existing commercial solutions.
We develop the compact and robust modular flight laser system. Three modules will provide the light fields for laser cooling of 87Rb atoms in 2D- and 3D-magneto optical traps, Raman interferometry, and state detection during the flight. This poster explains our design and assembly, presents results of characterization and outlines requirements caused by the aircraft conditions.
This project is supported by the VDI Technologiezentrum GmbH with funds provided by the Federal Ministry of Education and Research (BMBF) under grant number 13N16518.
