Fig. 2. (a) Measured self-frequency shift (SFS) of soliton frequency ν_soliton as a function of laser output power (blue dots) and quadratic polynomial fit. (b) Soliton pulse width (T_0) (Eq. 2) and fourth-order polynomial fit (red). (c) Normalized spectral power (blue) and soliton angular frequency (ν_soliton red dashed) defined as the spectral amplitude’s centroid frequency (Eq. 5) at Pavg = 623 mW. (d) cavity roundtrip group delay dispersion (GDD) and (e) third-order dispersion (TOD) as a function of frequency. (f) contribution to the carrier-envelope offset phase (CEP) on a semilogarithmic scale.
