'''9/4/14'''
Previous table is just raw data and doesn't include adjustments for optical losses of stokes and pump. See data [[File:633_data.xlsx|here]] for adjusted version and with useful statistics. Josh has been gone starting this week. Very sad, although productivity is at an all time high. I've got classes again which means less time in lab though. I've spent the week mostly doing a bit of data analysis and trying to get the 1555 beam up and running again--I want to see how much that affects 633 generation if I can simultaneously lock 1555 and 1064. It took about a day to re-align the 1555. I could tell at some point I was getting a small signal on the photodiode, but it was so mis-aligned it was hard to optimize it at all. Eventually I moved the photodiode just past the transmitted 1555 side of the cavity and lined it up with the HeNe (which is a reasonable marker of where the 1555 should be if it's making it through the cavity. Moving the photodiode reduced a lot of the optical losses and I took off the ND filter. I was still getting a small signal that was hard to optimize, but looking at the ramping signal simultaneously proved useful. I knew a useful scale for 1555 peaks would fall within half a ramping period, so by adjusting the scale and then 1555 alignment I could eventually see peaks and optimize as usual. Not only was it very mis-aligned the but the oscilloscope settings were really off so I wouldn't have been able to see much anyway. I'll try to remember that for next time.
1555 is aligned now, although not locking. I'm trying the vescent box right now and hoping I can get that working, although I might have to switch back to the homemade boxes as before.
