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.
