Subject: Power Output of 495 mW NPRO 

We characterized the power output vs. drive current of the 495 mW NPRO laser for the gyro experiment. The current supply  goes up to 1.00 A. Here is our data:

C = [0.46 0.52 0.60 0.66 0.74 0.80 0.88 0.94 1.00];
Pd = [2 18 38 55 71 93 110 125 146];
Pu = [2 20 39 56 72 94 110 126 147];

C is drive current, Pd is lower limit on power output in mW, and Pu is upper limit.

We graphed the results and fit a line to it. The slope is 261.5 mW/A, and the intercept is -118.2 mW. The graph is attached.
