Dk. Skripov et Va. Trofimov, The effect of the absolute phase on the spectrum of a femtosecond pulse propagating in a nonlinear medium, TECH PHYS L, 27(7), 2001, pp. 575-578
It is shown that the spectrum of a femtosecond light pulse propagating in a
nonlinear medium depends on the absolute phase. As the propagation distanc
e increases, the effect of the absolute phase of the light pulse on its spe
ctrum may either decrease or increase. (C) 2001 MAIK "Nauka/ Interperiodica
