Mode matching solution for Cavity |

Goals and restrictions:
- Use the fewest lenses as possible.
- The beam widths in both onward and reflection direction should be such that there is a 5-inch space somewhere where we can put in the faraday isolator which has an aperture size of 3 mm and intensity limit of 500 W/cm^2.
- The lens should not be closer than 1.5 inches from each other or to the EOM mount or cavity edge.
- Choose a lens from a list of focal lengths available in west bridge labs.
- Find the best overlap with the target beam of 18 um at the cavity waist with the most sensitivity with respect to lens positions.
