Abstract

The invention relates to a head for focusing a laser beam, including a collimator lens (13) and a focusing lens (14), wherein the collimator lens (13) and the focusing lens (14) are made from ZnS and have a peripheral thickness of at least 5 mm. In addition, a folding mirror (15) operating at an angle of incidence (#) of between 40 and 50° is provided on the laser beam path inside the focusing head between the collimator (13) and focusing (14) lenses. The invention further relates to: laser beam cutting equipment including a solid-state laser (SL) device emitting a laser beam having a wavelength of between 1.06 and 1.10 µm and a power of between 0.1 and 25 kW, a focusing head according to the invention, and a carrier fiber (CF) connecting the solid-state laser (SL) device to the focusing head such as to carry the laser beam emitted by the solid-state laser (SL) device to the focusing head.
