Abstract

Summary form only given. Measurement and control of the cartier-envelope phase (CEP) of high-intensity few-cycle laser pulses are required to precisely control the nonlinear interactions. The beat signal between the fundamental and its second harmonic, was used as the feedback signal to control the slip of the CEP of femtosecond laser oscillators. Here, we report the first measurement of the changes of the CEP on a single-shot basis. Spectral interferometry (SI) between the white-light continuum and its second harmonic was used for the single-shot measurement of the CEP. We consider a pulse with a broad spectrum ranges over one octave containing the red component (840 nm) and the blue component (420 nm).
