Retook beam profile coming out of SHG with everything in place. SHG Profile data can be found at Nextcloud/GQuEST/B102/SHG/SHG\ Beam\ 20Profile/SHG_Profile.ipynb. Will use this to match to the fiber inputs at the end of the SHG farm. All 4 paths on the SHG farm should be within an inch of each other so 1 MM solution before the first 50:50 should be sufficient. Will also post a solution for the two lens on either side of the AOM.
The input couplers for fibers we have want ~500 um size beams at the input. The attached photos show an approximate solution in JAMMT, and its experimental implementation. Discrepency arises from the uncertainty of the length in the path from the PBS to the input couplers.
Then I came up with an approximate solution for the lenses before and after the AOM. The full_jammt photo shows this to scale with the space we have on the sled. I think this will work. Ready to fire up an AOM now.
I also noticed a mistake on the SHG sled that had the path lengths differing by a couple inches that has been corrected.
