Abstract

A method and system for spot size selection wherein an indication of a spot size selection is received and a spot size is generated corresponding to the spot size selection by propagating an optical signal via one of the claddings of a dual-clad optical fiber. The system for spot size selection includes a plurality of lens arrays, at least one galvanometer, and a plurality of dual-clad fibers to propagate an optical signal from one of the plurality of lens arrays.

Claims (24)

1. A method for spot size selection, the method comprising:

receiving, at an optical system, a spot size selection;

generating a spot size corresponding to the spot size selection by propagating an optical signal using a first cladding of a dual-clad optical fiber;

receiving, at the optical system, a second spot size selection; and

generating a second spot size corresponding to the second spot size selection, by propagating the optical signal using a second cladding of the dual-clad optical fiber.

2. The method of claim 1 , wherein the propagating the optical signal using the first cladding of the dual-clad optical fiber comprises:

propagating the optical signal using an inner cladding of the dual-clad optical fiber.

3. The method of claim 1 , wherein the propagating the optical signal using the first cladding of the dual-clad optical fiber comprises:

propagating the optical signal using an outer cladding of the dual-clad optical fiber.

4. The method of claim 1 , wherein propagating the optical signal using the first cladding of the dual-clad optical fiber comprises:

propagating the optical signal through at least one of a plurality of lens arrays.

5. The method of claim 1 , wherein the generating the spot size is in response to the receiving, at an optical system, the spot size selection.

6. A method for spot size selection, the method comprising:

receiving, at an optical system, a spot size selection;

selecting a dual-clad optical fiber based on the spot size selection, the dual-clad optical fiber comprising an inner cladding and an outer cladding; and

generating a spot size corresponding to the spot size selection by propagating an optical signal using a cladding of the selected dual-clad optical fiber;

receiving, at the optical system, a second spot size selection; and

generating a second spot size corresponding to the second spot size selection, by propagating the optical signal using an other cladding of the dual-clad optical fiber.

7. The method of claim 6 , wherein the propagating the optical signal using the cladding of the selected dual clad optical fiber comprises:

propagating the optical signal using the inner cladding of the selected dual-clad optical fiber.

8. The method of claim 6 , wherein the propagating the optical signal using the cladding of the selected dual-clad optical fiber comprises:

propagating the optical signal using the outer cladding of the selected dual-clad optical fiber.

9. The method of claim 6 , wherein propagating the optical signal using the cladding of the selected dual-clad fiber comprises:

propagating the optical signal through at least one of a plurality of lens arrays.
