Today we replaced one mirror shown in the attached figure 1. The replaced one is pointed out by a black circle. This work broke the alignment of SHG, but we recovered it in the end.
Here I attached the simulation result of optocad, which tells us the beam going to this mirror with a beam waist of only 10um. As shown in the attached figure 2.
Future work:
We will increase infrared power to have at least the same green power as before.
Characterize the beam transmitted by this mirror.
