Filter Cavity
[Daniel,Torrey]
Construction of the first filter cavity has begun. We mounted all the required optics leading up to the cavity this morning. Now we have light from the power distribution center in a 5m fiber piped over to the other end of the table, going through both EOMs, and into the filter cavity. We are ready for the good mirrors now.

We moved the sled with the filter cavity to the cleaner table (table directly to the left when entering the room) and installed 3 newport 1550 laser line mirrors at each point on the filter cavity except for the input. We used the whole punched IR card to allow the input beam to enter and aligned the reflection of the 3 mirrors, i.e. one round trip in the cavity, to match the input beam. The beam incident on the cavity is now from the path of the power distrubution center previously used for Daniel's crusher tests.
