==Things to Do/Check==
*Use beam chopper on 780. Translate iris in front of PVC pipe to see if signal is from a beam or scatter. Try different filter combinations. Calculate angular positions of second order diffracted beams--are they close to where 633 should be?
*Why is 1064 current driver fluctuating?
*Get a really big lens before the 633 detection photodiode.
*Measure 780 power before and after cavity; see changes with cavity piezo
*Why is reflected 1064 signal fluctuating in power so much?
