Locking of multiple lasers to an Optical Frequency Comb

  • Author: Benjamin Sprenger, Bastian Hacker
In the Quantum Dynamics group headed by Professor Gerhard Rempe at the Max Planck Institute of Quantum Optics, multiple labs are moving towards locking all lasers required for cold atom experiments to a frequency comb (FC1500-250-WG). As opposed to locking to wavemeters, gas cells, and transfer cavities, the lasers now rely on the absolute stability of the frequency comb in transferring the stability of the MPQ hydrogen maser into the optical region. This transition has developed from many years of cooperation between Menlo and MPQ.
