摘 要：In a typical two-dimensional electronic spectroscopy（2 DES） experiment,the timing error of the coherence time and emission time when determining the absolute time zeros usually introduce extraneous spectral phase slopes and distort 2 D *** develop new methods to calibrate the absolute phase at the exact interaction region at sub-wavelength *** new method is easily implemented without supplementary instrumental construction,only relying additional scanning and data post-processing *** new proposed methods are expected to improve the phasing procedure in 2 DES in a more convenient way.
