[Aritomi, Yuhang]
According to Yuhang's simulation (latest simulation is a bit different from this), we installed superpolished lens (PLCX-25.4-149.9-UV, PLCC-25.4-515.1-UV) for injection telescope. Unfortunately the two lenses are very close with each other (Pic. 1) and cannot be moved. We'll continue this setup for the moment and if mode matching is problem, we'll think another configuration.
