摘要： The inventions disclosed by this application are for a cladding apparatus, a cladding head, and a method of cladding a relatively planar solid object such as a boiler waterwall. Cladding of non-horizontal surfaces is complicated by the effects of gravity as melted clad material trends to runoff the surface before the cladding material bonds to the appropriate location. The disclosed inventions overcome these limitations by controlling the relative angle of application by either rotating the workpiece or the cladding head through a pre-programmed sequence. Also presented in a compact design for a laser cladding head that facilitates such cladding by minimizing movement of the laser fiber and improves cladding speed over irregular shaped objects.

摘要： Laser energy is used to remove all the epithelium from a defined treatment zone on the surface of the cornea by focusing a laser beam on the epithelium and monitoring the vapor produced by ablation of the epithelium. The stroma is then sculpted to provide the desired refractive correction by dividing the ablation zone into a set of sub-zones and applying laser energy to each sub-zone in sufficient intensity for predetermined times to remove and reshape the surface of the stroma.
