One of the slower parts of collecting data is waiting for the pump laser to reach the desired detuning. I think that my current method could be improved significantly. Previously I was scared to make too big a jump of detuning in one shot, but I'm now convinced it's time to try.
Pasted below are two examples of the laser going from one detuning to another. The task is to find out the ratio of voltage shift to detuning shift, and add that factor into pumpLaserControl.c program. Then when the laser changes voltage to get to a given detuning, it will be calculating the needed change in voltage based on this ratio.
Again, @nstamos20, I think this is a fairly straightforward change that you can implement to help yourself get familiar with the code.
