Interference Filter Stabilized ECDLs at Lithium D-Line Wavelength — •Tobias Eul, Jan Phieler, Benjamin Gänger, and Artur Widera — Technische Universität Kaiserslautern, FB Physik, Erwin-Schrödinger-Str. 46, 67663 Kaiserslautern, Germany

Laser cooling requires narrow linewidth laser sources with the possibility to precisely control the output wavelengths. Recently a diode laser design based on an interference filter stabilized linear cavity was introduced by X. Baillard et. al. [1].

Lasers based on this design have proven to provide superior stability and linewidth at a moderate cost realizing a simple and reliable alternative to the established standard Littrow configuration.

We report on the construction of such lasers operating at an emission wavelength of 671 nm, suitable for spectroscopy and laser cooling of Lithium atoms, and we present measurements of the beam characteristics.
