  • Method and apparatus for changing the length of a laser pulse
    Patent number: 7822093
    Abstract: The apparatus for extending or lengthening a laser pulse has a beam splitter. An incident laser pulse is split by the beam splitter into at least one first partial pulse and a second partial pulse. The first partial pulse is conducted through a delaying travel path section with a number of reflectors. The apparatus is characterized by a plurality of the variable delaying travel path sections which produce different length laser beam pulses from a single incident laser pulse.
