We predict several effects associated with the optical response of systems prepared in a nonequilibrium state by impulsive optical excitations. The linear response depends on the phase of the electric field even if the initial nonequilibrium state has only populations, no coherences. Initial quantum coherences induce additional phase dependence, which also shows new resonances in nonlinear wave mixing. In systems strongly driven by an external optical field, the field frequency generates a…

Nonlinear optics.

In this method, non-linear susceptibility tensors are introduced which relate the induced dipole moment to a power series expansion in field strengths and the various experimental observations are described and interpreted in terms of this formalism.
