Claim Text:
1. A total internal reflection high power laser tool, for use in hydrocarbon exploration, hydrocarbon production or the decommissioning of hydrocarbon wells, the tool comprising: a. a beam tube, defining a tool axis, the beam tube comprising a laser beam path for transmitting a laser beam within the beam tube and a fluid path for transmitting a fluid; b. a housing in fluid communication with the beam tube, the housing comprising a single and unitary total internal reflection polyhedron structure comprised of a material transmissive to the laser beam; and, a passage defined in part by a total internal reflection surface of the total internal reflection polyhedron structure, the passage in fluid communication with the beam tube fluid path and removed from the laser beam path; c. the laser beam path extending through a first surface of the total internal reflection polyhedron structure and into the material; d. the laser beam path extending to and from the total internal reflection surface and forming an angle of incidence θ e. the laser beam path extending from the total internal reflection material and exiting the housing along a straight path; the exiting laser beam path forming an angle of about 90° or less with the beam tube axis.
