Abstract
Femtosecond pulse shaping for time-to-space conversion of ultrafast optical waveforms is presented, analyzed, and experimentally implemented. Here the temporal pattern for the designed multiple pulses optimized with a preassumed Gaussian spectral distribution of an ultrashort pulse is described. With the simulation of a Gaussian spectral distribution, we realize that the uniformity of the generated multiple ultrafast temporal pulses is relevant to the repeated number, the accuracy of the transition points and the pixel number for the modulation periods of the mask in the spectral plane. Especially, the change of the Gaussian spectral phase of the modulated phase plate with the wavelength that many people do not consider formerly is analyzed in detail in this work. On the other hand, experiments of the shaped femtosecond pulse measurement with the frequency-resolved optical gating (FROG) characterization technique are given in this paper.
