In the optimal laser configuration (current = 1.503A, see alog7695), the power before ALS-FI2 was measured to be 39.7mW, while the power after the FI was measured to be 37.6mW. Thus, the throughput of the ALS-F12 was about 94.7%. The first jpg (532nmALSfI2FullCurrent.jpg) shows the beam profile after the ALS-FI2.

The first pdf (BeamProfile532nmRefALSFI2.pdf) is a graph displaying the mode measurement of the 532nm beam with ALS-F12 as a reference. Meanwhile, the second pdf (BeamProfile1064nmRefALSM1.pdf) is a graph displaying the mode measurement of the 1064nm beam with ALS-M1 as a reference. Using the 13.5% width (or 1/e^2 diameter) of both the horizontal and vertical profiles, the radii for the two profiles were determined at various distances from the respective reference points. In addition, the graph includes error bars of one standard deviation. A line of best fit was produced, and the difference between the line of best fit and the data points was plotted in the lower portion of both figures.
