Grating geometry is shown. Path differences along the length of the grating are one cause of the temporal smearing. The angle labeled as in the figure is actually negative , given the measurement convention described in the text.
Raw data obtained from streak camera for a 1800 lines/mm grating and a sweep time of 1 ns.
Temporal profile of a measured pulse. The sharp rise and fall of the intensity define the temporal width of the pulse.
Dependence of temporal dispersion on the number of grooves illuminated. Different gratings are employed to vary the number of grooves illuminated.
Dependence of temporal dispersion on the number of grooves illuminated. Masks are used to restrict how much of the grating is illuminated.
Dependence of temporal dispersion on spectral order.
Effect of a spatially nonuniform beam on the temporal instrument function. Variations in intensity across the grating result in temporal variation in the image.
