Setup and location of the beam was relatively simple. The X and Y movements were used in conjunction with the 633nm target laser to center the beam on the camera chip. Once the beam was located and an approximate Z position was made using the target laser, the motorized Z stage was used to tweak in the image of the focused spot. We took profiles at 350 W, 500 W and 750 W. We could have taken a profile at 1000 W, but the tooling plate we were using for the beam dump was taking a beating and they didn’t want to push it higher than that. The images resulted in an elevated background, but it was not due to a lack of UltraCal.
