achievements

• try pumping STE membrane with FEL and detect THz emission with single shot EOS. No success.
• tried cross-polarization for a short time, no success either.
• reduced the PPL chirp to record single shot transient reflectivity data versus BAM for the night.

issues

• FEL on STE on sapphire show strong glowing so it's probably not the right regime to get THz
• we don't have a self referencing scheme to observe THz emission from PPL pump
