Determining carrier-envelope phase of an ultrashort laser pulse in quantum well via tuning inhomogeneity

When a few-cycle Inhomogeneous laser pulse propagates in parabolic quantum wells, a soliton pulse can occur after a certain propagation distance. The duration and peak intensity of such a soliton pulse are both sensitively dependent on the carrier-envelope phase (CEP) of the incident few-cycle pulse. This kind of CEP-dependence follows a sinusoidal modulation pattern with the Inhomogeneous degree of the incident laser field, which provides a route to determine the CEP by just shaping the field's inhomogeneity analogous to that by using polar media. & COPY; 2023 Elsevier B.V.

Automated summary

When a few-cycle laser pulse with non-uniform field propagates in a parabolic quantum well, a soliton pulse can be generated after a certain propagation distance. The duration and peak intensity of this soliton pulse are strongly influenced by the carrier-envelope phase (CEP) of the incident pulse. The CEP-dependence follows a sinusoidal modulation pattern related to the inhomogeneity of the laser field, which allows for determining the CEP by shaping the field's inhomogeneity, similar to using polar media.
