TL;DR
This paper demonstrates that two-photon coherent control in a three-level system can mimic one-photon coherent transients in a two-level system, using shaped laser pulses and 2D spectral analysis.
Contribution
It introduces a novel method to replicate one-photon coherent transients through two-photon control in a three-level system, utilizing higher order chirps and spectral peak analysis.
Findings
Two-photon control projects one-photon transient behavior.
Higher order chirps simulate time and linear chirp effects.
Phase and amplitude are retrieved from 2D Fourier spectra.
Abstract
We show that two-photon coherent control in a -shape three-level system projects one-photon coherent transient in a simple two-level system. Higher order chirps of a shaped laser pulse play the roles of time and linear chirp in conventional coherent transients. In a devised scheme of a three-pulse coherent excitation experiment, the phase and amplitude of controlled transition probability is retrieved from a 2D Fourier-transform spectral peak.
