Vogt, C. Lisdat, T. Legero, U. Sterr, I. Ernsting, A. Nevsky, S. Schiller] We present the setup and test of a transportable clock laser at 698nm for a strontium lattice clock. Amaster-slave diode laser system is stabilized to a rigidly mounted optical reference cavity. The setup was transported by truck over 400km from Braunschweig to Düsseldorf, where the cavity-stabilized laser was compared to a stationary clock laser for the interrogation of ytterbium (578nm). Only minor realignments were necessary after the transport. The lasers were compared using a Ti:Sapphire frequency comb as a transfer oscillator. The generated virtual beat showed a combined linewidth below 1Hz (at 1156nm). The transport back to Braunschweig did not degrade the laser performance, as was shown by interrogating the strontium clock transition. Springer-Verlag, 2011 Vogt S.
