On the nature of the coherent artifact

Lebedev, M. V.; Misochko, O. V.; Dekorsy, T.; Georgiev, N.

The coherent interaction of femtosecond laser pulses in the pump–probe regime has been experimentally studied in the time domain by monitoring light reflection from a tellurium single crystal. The optical response of the probed medium exhibits periodic variations at a frequency equal to that of the exciting laser radiation. Experimental dependences of the observed "coherent artifact" on the pump/probe intensity ratio, the number of accumulated pulses, and the mutual orientation of the polarization vectors of electromagnetic fields and the crystallographic axes are well described by the proposed phenomenological model.
