Abstract
A laser beam delivery system that uses total internal reflection inside prisms to redirect the high powered broadband output laser power from a laser beam source to the intended target. An articulated arm having straight segments connected end to end by rotatable joints attaches to a laser source that produces a laser output beam having at least two wavelengths. A prism is located at each joint wherein the laser output beam travelling down each of the segments is re-directed down the subsequent segment. The prisms are oriented to re-direct the laser beam by total internal reflection. Anti-reflective coatings are formed on each prism surface where the beam enters and exits each of the prisms.
