Gaussian 2D Beam Fit

Fit a 2D Gaussian beam and read the fitted beam parameters.

Learn how to use WaveRay for Gaussian 2D Beam Fit with real, manually matched screenshots. This tutorial covers setup, execution, result interpretation and practical checks.

What this tutorial covers

Fit a 2D Gaussian beam and read the fitted beam parameters.

Before you start：You need access to the product and should ideally follow the tutorial using your own real parameters or data. The screenshots below were manually rematched to avoid the image/topic mismatches seen in the previous version.

Step-by-step workflow

1Open the module

Open Gaussian 2D Beam Fit. Confirm that the visible page really matches the tutorial topic before changing any settings.

2Configure the input

Prepare and check the beam image or related data plus the fit parameters required by the tool.

3Run and watch the status

Import the data, run the Gaussian-beam fit and inspect the fitted result. Watch the visible status, plot or log area while the workflow is running.

4Inspect the result

Pay special attention to the fitted 2D Gaussian parameters and the corresponding result view.

5Verify and iterate

Check that the beam image is not heavily clipped before fitting, or the fitted parameters can be misleading. Change one meaningful parameter and rerun so you can verify whether the output changes in the expected direction.

How to read the result

  • The main output of this workflow is the fitted 2D Gaussian parameters and the corresponding result view.
  • Read the result together with the exact inputs used for the run; a screenshot alone rarely tells the whole story.
  • Check that the beam image is not heavily clipped before fitting, or the fitted parameters can be misleading.

Troubleshooting & practical tips

  • If nothing changes, first confirm that the correct module is open.
  • If the output looks unrealistic, check units, field mapping and input scale first.
  • For comparisons, change one key parameter at a time whenever possible.
