摘要: Short laser pulses are able to generate material excitations with a well-defined phase which is imposed by the optical excitation source. The generated coherent superposition state be described as an polarization exists only in non-equilibrium situations. coherence, i.e., relations between transitions that originate from excitation, leads several interesting effects time-resolved linear and nonlinear spectroscopy. In this article, basic principles underlie these transients introduced examples presented.
