OPTICAL SYSTEM FOR SHAPING AND GUIDANCE OF A LASER RADIATION BEAM Russian patent published in 2023 - IPC G02B27/09 G02B17/06 

FIELD: laser technology.

SUBSTANCE: optical system includes a laser fibre module with a fibre-optic terminal including optic fibre. At the output of the optical system, a beam reflected from a secondary mirror is incident on the main optical mirror structurally linked with a pre-guidance apparatus, from the reflecting surface whereof, made in a concave off-axis parabolic shape with a focus F of a complete parabola, a low-divergence laser beam incident on the image plane exits. The output optical axis is parallel to the central optical axis of the rectilinear optical fibre segment distanced from the axis of the complete parabola. The emitting end of the fibre optic terminal core is distanced by L from the point of intersection of the central optical axis with the reflecting plane of the secondary mirror. An additional secondary mirror is added. The main optical mirror is structurally linked with a scanning apparatus.

EFFECT: creation of a compact telescopic optical system based on fibre lasers and increase in the directivity of the created beam due to the increase in the accuracy of adjustment and scanning.
