Procurement of a fully stabilized laser system Text automatically translated in your browsing language Automatically translated

The University of Hamburg intends to develop an experiment in which several catch-specific ion systems are connected via a fast optical interface. Cryogenic and room temperature radiofrequency ion trans are used, which are specifically charged by photoionization specific isotopes of barium, together with laser cooling and optical quantum status manipulation. The state preparation and manipulation as well as the generation of entanglements are carried out by excitation of optical transitions in the ion. In order to address the numerous, narrow optical transitions of the neutral and simply ionized barium atoms, a system of external stabilized lasers is required. Since the project will focus on the development of ion trans and quantum optics protocols, a complete stable laser system is needed to cover all relevant optical transitions of the neutral and simply ionized barium atom. The lasers must therefore be tuned to the specified frequencies and stabilized with an absolute accuracy of 2 MHz or better. In order to enable the research focus on the development of optical interfaces, the entire laser stabilization must be carried out specifically in such a way that all lasers involved are secured relative to an external reference, since there is no simple atom-based blocking system for the simply ionized barium. The lasers must be sensitively tunable near the resonance frequency, provide narrow line widths for off-resonance excitation schemes and have high amplitude stability.
