Drew some new mounting scheme for the DOPO cavity; main revisions with respect to the current mount are -->

• Side mounts for both mirrors (instead of vertical)
• Both mirror mounts are the same (3-axis polaris K1) so both mirrors need to be attached properly
• Improved access to align crystal using newport 9031 (6 axis displacement mount), which is crucial to make the DOPO fields co-resonant

Attachment 1 illustrates the design; shows three views of the same assembly.

Concerns: mechanical noise from side mounted mirrors ... for this, there could be a solid piece which makes a rigid connection between the two mirrors (that's why they are upside down) and perhaps between the two tall posts (so S-shaped as viewed from the top)? Still working on this.
