Pengbo, Simon

Today, with the very much appreciated help from Manuel, we could start the translation-scans of the razor blade in horizontal direction at different Z-values in order to analyze the beam-profile automatically.
For the measurements itself, the powermeter is connected via a BNC cable to the DC-port of the LabView program.

Pengbo has written a Python-script to fit several of those scans at once so that we can easily get the results.

The laser-power of the pump beam is set to be ~110 mW for the entire measurements.

We started with our measurements actually in the area where the waist of the beam is supposed to be (Z-distance = 2mm, dZ = 0.1 mm, Zcenter = 74.1).
The next set of measurements will be over a wider range in Z further away from the waist.
