Linewidth-deduction method for nonlinear optical spectroscopy with transform-limited light pulses

Abstract

We have developed a Fourier-deconvolution-based linewidth-deduction method for nonlinear optical spectroscopy with transform-limited light pulses. The phase-retrieval problem involved in this method was solved with a phase-retrieval procedure based on the maximum-entropy model. Our proposed method can also help one to surpass the resolution limit set by the uncertainty principle when the amplitude line-shape function of the laser source can be fully predetermined.
