| Abstract: | Ultrafast temporal unequally-spaced spacetime conversion and recognition technique for Dammann-type filters is analyzed. The multiple pulse Dammann-type filter for specific unequally-spaced and equal-intensity filter were designed.With the simulation of a Gaussian spectral distribution,the correlation between the perfect uniformity of the generated multiple ultrafast temporal pulses and the repeated number of modulation periods of the mask in the spectral plane is discussed.Moreover,experimental result of recognizing the two ultrafast femtosecond pulses by the frequency-resolved optical gating(FROG) technique is also given. |
