Beschreibung
Zusammenfassung:	A laser system comprising: a laser operable to generate a laser beam; an optical system comprising a first optical element and a second optical element; and an output through which the laser beam exits the laser system; the laser, optical system and output arranged such that the laser beam travels to the first optical element, the second optical element and the output sequentially; wherein the first optical element has a first focal length, the second optical element has a second focal length equal to the first focal length, and the second optical element is spaced from the first optical element by a distance of two times the first focal length.
