Influence of precursor fields on ultrashort pulse autocorrelation measurements and pulse width evolution.
The influence of the precursor fields of a double resonance Lorentz model dielectric on ultrashort pulse autocorrelation measurements and the resultant dynamical pulse width evolution is presented.
متن کاملUltrashort pulse measurements by interferometric spectrogram.
We experimentally demonstrate that an interferometric spectrogram (i.e., fringe- and frequency-resolved autocorrelation trace) with high signal-to-noise ratio can be processed by three different procedures to accurately retrieve the spectral phase profile. We also show that the data redundancy built in the interferometric spectrogram permits simultaneous retrieval of multiple spectral phase sol...
متن کاملUltrashort Optical Pulse Measurements by Inteferometric Spectrogram
We experimentally demonstrate that an interferometric spectrogram of the signal pulse can be processed differently to obtain the spectral amplitude and(or) phase profile(s). Consistency between the results obtained by frequencyresolved optical gating (FROG) and modified interferometric field autocorrelation (MIFA) methods is confirmed. We also show that the robustness of MIFA technique against ...
متن کاملSensitive ultrashort pulse chirp measurement.
The chirp of an ultrashort laser pulse can be extracted with high accuracy from a modified spectrum auto-interferometric correlation waveform by using a new time domain algorithm that allows signal averaging. We display results revealing high sensitivity to chirp even with signal-to-noise levels approaching unity. Correction algorithms have been developed to accommodate signal distortion arisin...
متن کاملNovel method for ultrashort laser pulse-width measurement based on self-diffraction effect.
Previous pulse-width measurement methods for ultrashort laser pulses have broadly employed nonlinear effects; thus any of these previous methods may experience problems relating to nonlinear effects. Here we present a new pulse-width measuring method based on the linear selfdiffraction effect. Because the Talbot effect of a grating with ultrashort laser pulse illumination is different from that...
