I redid the mode matching into the ovens to account for the dispersion of the material affecting the Rayleigh range (like this)
I used Zr = L_crystal / 2 / n
Scratched in favor of the following:
f=100mm at 0.47 m
f=75mm at 0.758 m
This works well with the current table layout.
taking Zin at PMC to be 371^2*pi/1.064 um
and Zoven to be 1.8*10000/2 um, about 36-37 inches from the PMC
