Abstract

In order to study how to shape femtosecond pulses with space-time conversion technique,combining theoretical analysis with computer simulation,femtosecond pulse shaper of 4f system applying Dammann-type filters as mask was analyzed. Firstly,Dammann-type filters including equally-spaced and equal-intensity gratings and unequally-spaced and equal-intensity gratings were designed with gradient algorithm. Then,the relation among the generated multiple ultrafast temporal pulses,the periodic repetition number,the spacing between the components and the wavelength in the spectral plane was discussed. The results showed that the perfect uniformity of the output pulse trains was strongly affected by the number of periodic repetition number. The efficiency and uniformity of the resultant output pulses became lower because of the spacing between the components and the wavelength effect.
