output filter cavity lock with frequency of laser
Locked the cavity with the DC modulation port of the ULN15TK laser. Couple take aways:
-The UGF is pushed to ~2kHz (was ~1kHz).
-Some very strong peaks introduced via this port at ~830 Hz, 1.6 kHz, etc...
-the lock is more resilient against sound, but not immune.
