The new QCL laser 0922 was installed in the setup to replace the broken 0920 unit and has been turned on and its working. Thermal paste got on the output lens during storage/transport and but we cleaned off using tissue and isopropanol. The main path alignment has been completed but the pickoff paths havent been checked and lenses havent been replaced. The new unit requires a slightly different lens position described in the yaml file which will hopefully be installed tomorrow.
