Abstract

Mastering tools and systems and methods for forming a cell on the mastering tools are provided. An exemplary method includes emitting a first laser light pulse from a laser for a first predetermined time interval such that at least a portion of the first laser light pulse forms the cell on the mastering tool. The cell has an opening size within a range of 10-100 micrometers and an aspect ratio less than or equal to 1.25.

Claims

1. A method for forming a cell on a mastering tool, comprising:

emitting a first laser light pulse from a laser for a first predetermined time interval such that at least a portion of the first laser light pulse forms the cell on the mastering tool, the cell having an opening size within a range of 10-100 micrometers and an aspect ratio less than or equal to 1.25.

2. The method of claim 1, further comprising receiving the first laser light pulse at an optical component and directing the first laser light pulse from the optical component to the mastering tool.

3. The method of claim 2, wherein the optical component is at least one focusing lens.

4. The method of claim 3, wherein the at least one focusing lens has a predetermined focal length.

5. The method of claim 4, wherein the predetermined focal length is in a range of 40-80 millimeters.

6. The method of claim 4, wherein the mastering tool is at a distance from the focusing lens less than or equal to the predetermined focal length of the focusing lens, or greater than the predetermined focal length of the focusing lens.

7. The method of claim 1, wherein a focused spot of first laser light pulse is at a first depth within the mastering tool.

8. The method of claim 1, further comprising adjusting a size of the first laser light pulse to a predetermined size or a mode shape of the first laser light pulse to a predetermined mode shape, utilizing a first device.

9. The method of claim 1, wherein the first laser light pulse has an average power level within a first predetermined average power range.

10. The method of claim 2, wherein the first predetermined average power range is 1-100 watts.

11. A system for forming a cell on a mastering tool, comprising:

a laser configured to emit a first laser light pulse for a first predetermined time interval such that at least a portion of the first laser light pulse forms the cell on the mastering tool, the cell having an opening size within a range of 10-100 micrometers and an aspect ratio less than 1.25.

12. The system of claim 11, further comprising an optical component configured to receive the first laser light pulse from the laser and to direct the first laser light pulse toward the mastering tool.

13. The system of claim 12, wherein the optical component is at least one focusing lens.

14. The system of claim 13, wherein the at least one focusing lens has a predetermined focal length.

15. The system of claim 14, wherein the predetermined focal length is in a range of 40-80 millimeters.

16. The system of claim 14, wherein the mastering tool is at a distance from the focusing lens less than or equal to the predetermined focal length of the focusing lens, or greater than the predetermined focal length of the focusing lens.

17. The system of claim 11, wherein a focused spot of first laser light pulse is at a first depth within the mastering tool.

18. The system of claim 11, further comprising a first device configured to either adjust a size of the first laser light pulse to a predetermined size or a mode shape of the first laser light pulse to a predetermined mode shape.

19. The system of claim 11, wherein the first laser light pulse has an average power level within a first predetermined average power range.

20. The system of claim 19, wherein the first predetermined average power range is 1-100 watts.

21. The system of claim 11, wherein the laser further configured to emit a second laser light pulse for a second predetermined time interval such that at least a portion of the second laser light pulse further forms the cell on the mastering tool.

22. A mastering tool, comprising:

a cylindrical drum having at least one cell, the cell having an opening size within a range of 10-100 micrometers and an aspect ratio less than or equal to 1.25.

23. A mastering tool, comprising:

a plate member having at least one cell, the cell having an opening size within a range of 10-100 micrometers and an aspect ratio less than or equal to 1.25.
