Two-color spectroscopy for laser stabilization to the ytterbium 1S0-3P1 intercombination line — •Christian Halter, Bastian Pollkeneser, Kapilan Paramasivam, Bastian Schepers, Tobias Franzen, Gregor Mura, and Axel Görlitz — Institut für Experimentalphysik, HHU Düsseldorf, 40225 Düsseldorf

We present a scheme for frequency stabilization of multiple lasers that are resonant to transitions and originating from a common ground state. For the detection of weaker transitions we are harnessing the high signal to noise ratio provided by a strong transition. Doppler reduced spectroscopy is performed on an atomic beam by detecting the fluorescence of a strong dipole allowed transition. Individual error signals for this transition as well as additional weaker transitions are recovered from the strong fluorescence signal using lock-in techniques. We demonstrate the application to strong 1S0-1P1 transition and the 1S0-3P1 intercombination line of ytterbium in the context of MOT.
