The study of numerical character for femtosecond pulse shaping

This paper describes the generation of shaped femtosecond multiple pulses by using the phase-only Dammannfilters in 4f femtosecond shaper and gives the experimental result of femtosecond pulse characterization by the frequency-resolved optical gating (FROG) technique. With the theoretical simulation, it concludes that the quality of the generatedoutput array is relevant to the number of pixels and the spacing between the components.
