"The dipole response of an excited quantum system gives direct insight into the electron\r\ndynamics triggered by the incoming light. Spectroscopy techniques such as (attosecond)\r\ntransient absorption spectroscopy make use of the fact that the dipole response leaves\r\nits characteristic fingerprint on the transmitted light. In this work, a general and comprehensive\r\nmodel is introduced, which allows for an analytic description of dipole dynamics\r\ntriggered and modified by two ultrashort light pulses in both time and frequency\r\ndomains. Based on this description, a two-dimensional spectral representation of time\r\ndelay–resolved absorption data is developed. The power of the method to separate different\r\npathways of light–matter interaction, which allows for their individual investigation,\r\nis demonstrated experimentally by studying electronic wave packet dynamics in doubly\r\nexcited helium and inner-valence excited xenon.\r\nFurthermore, an in situ technique for characterization of the intense dressing laser pulse\r\nthat drives (nonlinear) quantum dynamics in time-resolved absorption experiments is derived\r\nfrom the same analytic model and demonstrated experimentally. The possibility to\r\ncharacterize these ultrashort strong-field laser pulses directly within the spectroscopy target\r\nenhances the scope of transient absorption spectroscopy as it allows for the precise\r\nmeasurement and control of electron dynamics and increases the comparability between\r\nexperiment and theory."^^ .
