Abstract

A laser ablation system includes a first embodiment of a nozzle assembly where a laser beam is emitted through the nozzle assembly to remove materials on a target. The nozzle assembly includes a nozzle having a top end, and a window placed on the top end of the nozzle. The window includes one or more apertures and the laser beam is emitted through one of those apertures. Another laser ablation system includes a second embodiment of a nozzle assembly where a laser beam is emitted through the nozzle assembly to remove materials on a target. The nozzle assembly includes a nozzle having one or more channels at a top end of the nozzle. The nozzle assembly also includes a window that is placed on the one or more channels. A gas flows through the one or more channels and that gas flow reduces debris deposition on the window. Yet another laser ablation system includes a third embodiment of a nozzle assembly that includes a nozzle that has a central channel aligned longitudinally through which said laser beam travels from a top end of said nozzle to a bottom end of said nozzle. In this embodiment, the central channel of the nozzle is threaded.

Claims (16)

1 - 6 . (canceled)

7 . Within a laser ablation system, a method to reduce debris deposition at one or more points on a window, comprising:

generating a laser beam; and

emitting said laser beam through an aperture at a particular one of said one or more points on said window.

8 . The method of claim 7 wherein a diameter of said aperture is greater than or equal to a diameter of said laser beam.

9 . The method of claim 7 wherein a diameter of said aperture is less than a diameter of said laser beam.

10 - 20 . (canceled)

21 . A method to produce a nozzle assembly of a laser ablation system, comprising:

inserting an aperture in a window;

depositing said window on a top end of a nozzle,

wherein a laser beam is emitted through said aperture of said window.

22 . The method of claim 21 wherein a diameter of said aperture is greater than or equal to a diameter of said laser beam.

23 . The method of claim 21 wherein a diameter of said aperture is less than a diameter of said laser beam.

24 . The method of claim 21 wherein said window is transparent.

25 . The method of claim 21 wherein said window is opaque.

26 . The method of claim 21 wherein a shape of said aperture is any one of a circle, a square, or a rectangle.
