Subject: Weekly Summary 1 

Over the course of the first week here I've done several things. The first thing we're going to try to do in the lab (once we have all our parts in) is lock a simple cavity using Pound-Drever-Hall. I've been reading some of the literature on that and familiarized myself with that technique. Through these readings, I've come across various terms and equipment used in optical setups that I was unfamiliar with, so I've become acquainted with those. I attended the laser safety training meeting and have started to find my way around the lab. Connor and I also began characterization of the Nd-YAG laser. While I will not be working with that one, I will have to do the same thing for the one I will be working with. We first made some measurements of its output power versus the drive current, and results from that can be found in an entry to the eLog on 6-23-09. Today we are going to use the BeamScan to figure out the divergence of the laser.

Various other things that I've done over the past week include learning how to work with Matlab and Linux (both of which I am relatively unfamiliar with), and attending talks about the LIGO project by Dr. Weinstein.
