CEO phase /CEP
First paper in 1999 on carrier-envelope offset (CEO) phase control (also referred to as CEP control):
A novel concept for absolute optical frequency measurement and ultrashort pulse generation: DownloadRef. [113] (PDF, 258 KB)
A modelocked laser oscillator produces a pulse train with pulses separated by the pulse repetition rate period TR and described by the pulse envelope A(t), the electric field E(t).
