1. a method that is used for determining in a short pulse laser system minimum pulse width of a pulse laser beam makes that this minimum pulse width is explanation and the relevant dispersiveness of this pulse laser beam of passing through a diffraction optics assembly, and this method comprises:

  • Decision is formed on one in the surface of a target and peels off dimensional data;

    Determine an operative wavelength of a pulse laser beam;

    Decision is incident on the spot size data of this light beam on this target;

    Determine the tolerance data of this spot size of this incident beam;

    AndPeel off this operative wavelength of dimensional data, this laser beam, this spot size data of this laser beam and these tolerance data of this spot size based on this, to determine a minimum pulse width of this pulse laser beam.
