Subject: North path construction progress: PMC MM lenses  


I have added two lenses in order to create a waist of 330um for when the PMC will be implemented.

Not satisfied about the size of the beam. This has to be improved, but we are close enough. I am thinking

to put the PMC in place and mode match the laser beam to the PMC, in order to have a better reference.


The two lenses are 114.5mm and 401mm focal length rispectively, as shown in the attached schematic.


At moment the beam for the PMC (after the two lenses) is the following:
