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.

Delivery system for high power multi-wavelength laser systems

A filter system for reflectively blocking laser radiation in the visible spectrum includes a multilayer interference structure arranged for reflectively blocking a continuous band of wavelengths including the laser radiation and transmitting other wavelengths in the visible spectrum. The filter system is arranged to control transmission of the other wavelengths of the visible spectrum such that the filter system has an essentially neutral transmission color and maximum photopic transmission consistent with the band of wavelengths reflectively blocked.
