Abstract
(DE)
Ein Lasersystem mit einer kompensierten Optik enthält gemäß der Erfindung wenigstens ein optisches Element (4), das zur thermischen Kompensation einer durch den Laserstrahl hervorgerufenen Verformung der im Strahlengang des Lasersystems angeordneten optischen Elemente mit einer Wärmequelle (8) thermisch gekoppelt ist.
(EN)
Described is a laser system with compensated optics, the invention calling for the system to be fitted with at least one optical element (4) which is thermally linked to a heat source (8) to provide thermal compensation for the distortion, caused by the laser beam, of the optical elements located in the laser beam path.
(FR)
Un système laser à dispositif optique compensé contient selon l'invention au moins un élément optique (4). Pour compenser thermiquement une déformation des éléments optiques placés dans la trajectoire du système laser, due au faisceau laser, cet élément optique (4) est couplé thermiquement à une source de chaleur (8).
