摘      要：Characterization of the state of polarization(SOP)of ultrafast laser emission is relevant in several application fields such as field manipulation,pulse shaping,testing of sample characteristics,and biomedical ***,since high-speed detection and wavelength-resolved measurements cannot be simultaneously achieved by commercial polarization analyzers,single-shot measurements of the wavelength-resolved SOP of ultrafast laser pulses have rarely been ***,we propose a method for single-shot,wavelength-resolved SOP measurements that exploits the method of division-of-amplitude under far-field transformation.A large accumulated chromatic dispersion is utilized to time-stretch the laser pulses via dispersive Fourier transform,so that spectral information is mapped into a temporal *** calibrating our test matrix with different wavelengths,wavelength-resolved SOP measurements are achieved,based on the division-of-amplitude approach,combined with high-speed opto-electronic *** a proof-of-concept demonstration,we reveal the complex wavelength-dependent SOP dynamics in the build-up of dissipative *** experimental results show that the dissipative soliton exhibits far more complex wavelength-related polarization dynamics,which are not shown in single-shot spectrum *** method paves the way for single-shot measurement and intelligent control of ultrafast lasers with wavelength-resolved SOP structures,which could promote further investigations of polarization-related optical signal processing techniques,such as pulse shaping and hyperspectral polarization imaging.
