Abstract
Beam adaptation devices are disclosed for variable-astigmatic adjustment of electromagnetic radiation propagating along a beam axis of the beam adaptation device. The devices include a first astigmatism lens unit, which provides at least one first lens tiltable with respect to the beam axis for astigmatism adjustment, a divergence matching lens unit with a second lens for adjusting the divergence, wherein the distance between the second lens and the first lens along the beam axis is adjustable, and a second astigmatism lens unit with at least one third lens tiltable with respect to the beam axis for astigmatism adjustment. To adjust the magnitude of the electromagnetic radiation on the third lens, the distance between the second lens and the third lens along the beam axis is adjustable. The beam adaptation device can be used, for example, for astigmatic pre-compensation in frequency conversion.
