After the installation of the plexiglass enclosure, we proceeded with the optics and bench cleaning; then we mounted again the optics on the holders and we realigned the matching telescope.
In the attached plot there is the measurement of the waist size and waist position of the final beam.
The results are:
TElescope out
wox = 1.30 +/- 0.05 mm beam waist in the sagital plane
woy = 1.38 +/- 0.07 mm beam waist in the tangential plane
zox = 7430 +/- 160 mm distance from the telescope second mirror MT2 in the sagital plane
zoy = 6820 +/- 290 mm distance from the telescope second mirror MT2 in the tangential plane
consistent, in the limit of their uncertainty (1.5*Dzoy for zoy), with the wanted nominal values:
wox = 1.351 mm beam waist in the sagital plane
woy= 1.346 mm beam waist in the tangential plane
zox= 7344 mm distance from the telescope second mirror MT2 in the sagital plane
zoy= 7291 mm distance from the telescope second mirror MT2 in the tangential plane
We will proceed with the beam parameters optimization by matching it on the SDB1 beam.
