532 M2 Measurements |
|
|
Final M squared measurements were taken Wednesday, 3/29/23 by Peter and Ryan Hinosawa. 5 separate sets of data were taken, and upon discussion, we declared the plots shown below in attachment 1 and 2 as the final plots of our M squared measurements.
The optical design of the M squared measurement process is given in attachment 3. The laser and three lenses shown below are mounted on the optical table. The track is placed behind the third lens, and the camera is moved along the track to take successive measurements of the beam's width. This will allow us to see a change in the beam's width over its propagation direction.
The raw data is given in attachment 4 as a Beam_Data_8_3lens.txt file. This is eventually what gets used to generate the plots shown below.
The code to run the analysis on these measurements (as well as analysis on the Gaussian intensity profile fitting) can be found:
