measured gaussian beam radius

What I did : I measured gaussian beam radius and fited beam propagation using beam profiler and Python.

Why I did: trying for Pound-Drever-Hall method.

Experiments: I set up the following in a attached picture.

Result:The result of fitting is also in a attached picture.

Conclusion: I could have measured the beam radius.
