6. An optical arrangement for beam guiding of a light beam generated by a light source to a target location along a path distance
LS, comprising
at least one delay line having an input at which said light beam coming from said light source is split into a first partial
beam which additionally passes through said delay line at least once, thereby covering a path distance LD, and into a second partial beam that does not pass through said path distance LD, and an output at which said delayed first and said non-delayed second partial beam are combined so that the combined light
beam passes to said target location,
a beam guiding optic being present in said beam path and being designed in such a way that said light beam generated by said
light source has a predetermined beam width B at said target location, said beam guiding optic having at least one expansion
optic, which expands said light beam to a beam width B′>B, and said beam guiding optic having at least one compression optic,
with the result that said light beam has said predetermined beam width B at said target location.
