Very high power laser chamber optical improvements

摘要

An aspect of the disclosed subject matter includes a method of reducing the laser absorption of a beam reverser prism consisting of at least one of the following: increasing a first distance between a first incident point and a chamfered corner, wherein the first incident point is on a first reflective surface of the prism and the chamfered corner is formed between the first reflective surface and a second reflective surface of the prism, wherein the chamfered corner has a chamfered surface; increasing a second distance between a second incident point and the chamfered corner, wherein the second incident point is on the second reflective surface of the prism; and increasing a reflectivity of the chamfered surface of the chamfered corner of the prism. A method of determining a prime cut for an optical component is also disclosed. A laser including at least one prime cut optical component is also disclosed.

1. A method of reducing the laser absorption of a beam reverser prism consisting of the following:
increasing a first distance between a first incident point and a chamfered corner, wherein the first incident point is on a first reflective surface of the beam reverser prism and the chamfered corner is disposed between the first reflective surface and a second reflective surface of the prism, wherein the chamfered corner has a chamfered surface and wherein an input laser beam is directed through an input face of the prism to the first incident point, wherein the chamfered corner includes a polished chamfered surface having a finish substantially equal to a reflective surface finish of at least one of the input face, the first reflective surface or the second reflective surface.
