Characteristics of Output Pulse from a Grating Pair Stretcher with a Slit
Temporal characteristics of output pulse from a grating pair stretcher with a slit are investigated neglecting the spatial diffraction. And a theoretical model is established to expound the variation of pulse duration and the modulation on the pulse envelope similar to the diffraction characteristics in spatial domain. The modulation can be eliminated by appropriate soft slit. The condition, on which the slit has not much to do with spatial filtering, is discussed.
