It is demonstrated that for femtosecond supercontinuum generation in optical waveguides with nonresonant electronic nonlinearity the squared root-mean-square pulse duration varies near-parabolically with distance, irrespectively of spectrum ultra-broadening scenarios. The derived formulas for parabolic coefficients are applied to find the areas of spectral and energetic parameters of few-cycle pulses propagating in hollow capillaries filled with noble gases, where temporal pulse broadening, compression, or quasi-stationary propagation occur. Each regime is illustrated by the typical changes in the pulse electrical field and spectrum.
