OPO replacement - placement of lenses for OPO mode matching telescope
Marc and Yuhang
We have put two lenses for OPO mode matching telescope. They are LA1422 and LA1608, exactly the lenses suggested from simulation in elog2486.
After putting lens, we checked with sensor card and found the beam waist is about 5 holes after the second lens. This agrees with simulation.
