Abstract :
A number of applications ranging from high-resolution frequency-comb spectroscopy, coherent control with shaped femtosecond pulses to novel carrier envelope offset (CEO) sensitive experiments rely on femtosecond laser sources which are stabilized with respect to the CEO-phase and repetition rate. This paper investigates on an octave-spanning Ti:sapphire laser system that reveals its CEO-phase without any additional spectral broadening, delivering stabilized pulses with a duration as short as 4.4 fs and usable output power of 90 mW. With a piezo-driven repetition rate stabilization a fully controlled self-referenced octave-spanning frequency comb with about 80 MHz mode spacing is realized.
