keyword=Compton Cavity Having Some TroubleYou can see from the attached strip chart that the Compton laser cavity is sometimes (1) failing to lock promptly (see for example the period preceding 05:14) and (2) losing its lock prematurely (for example at ~05:00), even when beam current (purple line) is stable. Also, the power in the cavity seems unstable; it is not flat in a single locking cycle, and the average power fluctuates from lock to lock. Does the cavity need a serious retune?
