More 1064 laser problems today. Can't quite describe problem. The cavity peaks (without modulation) are very sensitive to cavity piezo position. Something doesn't look right about the peaks. They almost look like the laser is multimode, but checking with the OSA, it doesn't appear to be. I'm not sure what the problem is. I had a ton of trouble getting the peaks to be single mode, and when I did, it wasn't a very stable single mode. A slight change in the cavity piezo or in the alignment made a bigger-than-normal difference in the single-modeness.
