Abstract:
1. A surgical laser system including a scanning device for focusing a luminous beam into a selected range of an eye to be treated, comprising: a femtosecond surgical laser source that produces the luminous beam, the femtosecond surgical laser source being structured to produce photo disruptions within tissues of an eye to be treated upon focal application of the luminous beam to the tissues; entrance optics following the femtosecond surgical laser source into which the luminous beam first enters comprising at least a first optical element, the first optical element comprising a lens or non planar mirror; focusing optics by which the luminous beam emitted from the entrance optics is focused on the eye to be treated; a deflecting device arranged between the first optical element and the focusing optics to divert a focus position of the luminous beam that leaves the first optical element in a lateral direction, the deflecting device comprising a first movable reflective element movable about a first axis configured to deflect the luminous beam in an X direction and a second movable reflective element movable about a second axis that is substantially orthogonal to the first axis configured to deflect the luminous beam in a Y direction; the entrance optics comprising at least one movable optical element that is configured to be movable along an axis generally parallel to the luminous beam where the luminous beam passes through the entrance optics to the deflecting device to adjust the focus position of the luminous beam within a portion of the eye; a contact lens following the deflecting device and the focusing optics that is engageable with a cornea of the eye, the contact lens having a contact area by which contact with the cornea is made; and a beam splitter located between the deflecting device and the and the focusing optics at a location where the luminous beam exhibits substantially parallel light rays that directs observation beams from points in the cornea in a direction of a tube with an eye piece or an objective with a camera configured to permit monitoring of the cornea during application of the luminous beam to the cornea directly along an axis of the luminous beam as the luminous beam is applied to the cornea.
