About this protocol:' This protocol outlines the steps used to laser anneal nanoporous gold (np-Au). For more qualitative description please read Chapman, CAR. et al. Engineering on-chip nanoporous gold material libraries via precision photothermal treatment. Nanoscale. (2015)

List of Control Elements

1. Shutter Button: This button can be used to send a manual signal to the shutter. When the (BOOLEAN) toggle is TRUE the shutter is OPEN, when is it FALSE the shutter is CLOSE.

2. Program Rate: This indicator is the difference (in milliseconds) between the loop time and the previous loop time. This gives you a measure for how fast or slow the program is running. As long as the value is stable you do not need to do anything. If it starts increasing dramatically restart your program to clear the memory.

3. Abort: This button will abort the running processes. NOTE: This button does not turn off the laser or shutter the laser. This should only be used if you enter a bad loop.

4. Laser Port: This should be selected to the COM port that the laser USB connection is using. Typically COM4 on the set-up as it is used now.

5. H[1.1]: This is the height value (in millimeters) of your TOP LEFT sample in the array of patterns that you want to anneal.

6. W[1.1]: This is the width value (in millimeters) of your TOP LEFT sample in the array of patterns that you want to anneal.

7. Number of Columns: This is the number of columns in the array you are annealing.

8. Sample Spacing [X]: This is the spacing (in millimeters) between the MIDDLE of each sample in the columns (i.e. the distance between the middle of each sample on the top of your array).

9. W[1.n]: This is the width value (in millimeters) of your TOP RIGHT sample in the array of patterns you want to anneal. NOTE: This must be set even if you are not decreasing size in your array.

10. H[1.n]: This is the height value (in millimeters) of your TOP RIGHT sample in the array of patterns you want to anneal. NOTE: This must be set even if you are not decreasing size in your array.

11. Laser ON: This is TRUE when the laser is ON and FALSE when the laser is OFF. NOTE: Sometimes it gets stuck and needs to be manually reset.

12. Power at source: This is the current set value of the laser power at the source (in Watts).

13. Power at sample: This is the current set value of the laser power at the sample surface (in Watts).

14. Measure: This button will bring you to a screen capture of the current camera view. You can then draw a line on this screen capture and this will cause a distance (based on the currently selected objective [27]) to be displayed in [15].
