Subject: Figuring out how much astigmatism is hurting us 

Methods

  • Use the actual measured beam profile in X and Y directions.
  • Propagate them with the current position of lens.
  • Assume the position of cavity mirror and crystal as given by the second solution in BestSolutions.mat in the Jan 8th analysis which is implemented currently.
  • Calculate the overlap with target and position of waists in X and Y direction.

Conclusions

  • Astigmatism should not be hurting us significantly.
  • The mode matching in principle can be improved in the experiment.
