Laser Surgery

The basis for the use of medical lasers is the combination of precise focusing, optimum beam bundling and powerful laser protection. The installation of high-quality optics, e.g. aspheres, in the laser system enables the implementation of an effective, durable and safe laser for consistently best results and satisfied patients by correcting spherical imaging errors, so-called aberrations, aspheres significantly improve imaging results. The focus can be precisely centered, and the effectiveness of the laser increased as well as kept constant. A further advantage results from the compact design, since the use of aspheres requires quantitatively fewer lenses than, for example, the use of spherical lenses. Beam shaping systems are required for the perfect bundling of monochromatic light. With the help of products from asphericon's BeamTuning product range, an easy transformation of Gaussian laser beams into various Top-Hat profiles is achieved. With homogeneous intensity distributions, so-called Top-Hats, significantly better results can be achieved than with Gaussian profiles. They enable, for example, a high edge steepness of the laser beam and thus the quality of a cutting edge or even uniform illumination.
