The First Measurements with Octave-Spanning Femtosecond Laser Frequency Combs

March 13, 2004

Author(s)

Scott A. Diddams, David J. Jones

Here we describe in a historical manner the first optical frequency measurement measurements with octave-spanning frequency combs and the first measurement and stabilization of the carrier-envelope offset frequency for a train of femtosecond laser pulses.
