Patent ID: 8649413

Claim:
A high-powered laser beam focusing apparatus, comprising; (a) a laser having a beam delivery fiber for generating a laser beam; (b) a housing adapted to receive the beam delivery fiber, wherein the housing further includes: (i) a first chamber, wherein the chamber is adapted to receive a flow of pressurized gas; (ii) a second chamber; and (iii) an aerodynamic window positioned between the first chamber and the second chamber; and (c) a focusing optic connected to the housing and facing into the first chamber, wherein the focusing optic is operative to receive, focus, and redirect the laser beam into the aerodynamic window; and (d) a reimaging optic connected to the housing and facing into the second chamber, wherein the reimaging optic is operative to receive the laser beam exiting the aerodynamic window and reimage and redirect the laser beam onto a work surface.
