Subject: CCW Alignment 

 After I installed the mode matching lenses last week, I aligned the CCW beam into the cavity. The solid red lines in the picture below are the incoming beam, and I've included a picture of the CCD camera output on the monitor and the photodetector output on the oscilloscope. The beam is currently being scanned at .1 Hz. I've also aligned the beam coming out (dashed red line) and through the Faraday isolator and into the photodetector. I haven't had a chance yet to look at the output of this though.
