Abstract
The invention concerns an optical device and its application to generate an adjustable wave front deformation of a laser beam and thus to generate an adjustable beam spot geometry in the focal plane of laser optics. For this purpose, a device is provided which allows adjusting and modifying a laser beam in such a way that a beam spot, the shape of which can be adjusted continuously based on the original focal shape, is generated after focusing the beam, i.e. at least one dimension parameter of the shape of the beam spot has to be variable and adjustable so that the beam parameter product of the beam can also be modified without having to modify the focal position.
