It's C3:PSL-FSS_SLOWDC. I'm not keeping the cavity locked in order to avoid any heat absorption from the beam. I only lock the cavity when I check the SLOWDC level every hour.

Duly noted. I edited the entry accordingly.
SLOWDC is for thermal control on NPRO crystal. It is used for adjusting laser frequency.
