I screwed down the sled with the laser to the breadboard and aligned the laser into the bowtie cavity. The laser is centered through the input port, onto the crusher, and out of the 3rd port. The beam was diverging, so I then added a 1 m focal length lens before the final steering mirror. This lens did not affect the allignment of the beam. The beam is roughly 2 mm while hitting the crusher mirror and has a smaller, unmeasured waist after leaving the bowtie cavity. I plan on making some measurments next.
