Webb1 nov. 2011 · We demonstrate carrier-envelope phase (CEP) stabilization of a mode-locked Ti:sapphire oscillator with unprecedented timing jitter of eight attoseconds. The stabilization performance is obtained by a combination of two different stabilization approaches. In a first step the drift of the CEP is stabilized with a conventional feedback … Webb2. Approximation of slowly varying envelope . Let the carrier frequency of an optical pulse belong to the visible or infrared spectral range (Z ~10. 15 1. c ). Then the pulses whose …
