Either way, I still got really good contrast with the standing wave, and contrast with the larger FORT.

When the laser is pulsed, there is a different amount of power that gets through The AOM than when it is on CW. For Ch.C. the pulsed power is about 10% less that the CW power. For Ch.B. the pulsed power is about 5% higher than CW. This could cause some differences in what I set the power to. I want to check this every few days, because I think I'm getting slightly different numbers when I test it. I'm focusing the CW into a photodiode, and then switching to pulsed, seeing what the difference is. I got 15% instead of 10% for CH.B. yesterday...but I'll go with 10% for now.
It would be helpful if I could measure that pulse power by itself.
