===ECDL Tuning===
'''7/16/15'''
I tuned the laser by varying the current from 35mA to 120mA and kept the piezo at 2V for one scan and 35V for another. The 2V scan gave a little cleaner data and both gave nearly the same tuning rate of about -1.5 GHz/mA. The rate seemed to increase at higher currents. This tuning rate along with the piezo tuning rate implies that the piezo and current should be tuned with a ratio of about -.107 mA/V which is quite low compared to what I've been reading.
