Abstract
Methods and devices for expanding a laser beam are provided. In one aspect, a device includes a telescope arrangement having two spherical folding mirrors for expanding an incident collimated laser beam with a lens arranged in the divergent beam path downstream of the telescopic arrangement. The two spherical folding mirrors in the beam path are a first, convex-curved spherical folding mirror and a second, concave-curved spherical folding mirror, respectively. The lens has a spherical lens face for collimating the expanded laser beam from the telescope arrangement. The laser beam can be an ultraviolet (UV) laser beam.
