Abstract
Official abstract text for this publication.
An apparatus with a high power laser-mechanical bit for use with a laser drilling system and a method for advancing a borehole. The laser-mechanical bit has a beam path and mechanical removal devices that provide for the removal of laser-affected rock to advance a borehole.
First claim
Opening claim text (preview).
What is claimed: 1. A flat bottom fixed cutter laser-mechanical bit comprising: a. a bottom section having a central axis, a width and a flat bottom end, wherein the bottom end is configured to engage a borehole surface; b. a beam path channel defined, in part, by a plurality of beam blades, wherein the beam path channel forming a shape, wherein the shape includes at least one member of a group comprising: a rectangle and an ellipse extends across the width of the flat bottom en…
