Shiela reduced the 1064 nm laser power coming from the PSL going into the vacuum system via the PSL's rotation stage down to 108 mW (measured down stream of the PSL rotation stage, H1:IMC-PWR_IN_OUT16) to 108 mW, then Peter and I locked out the rotation stage controller. We've confirmed that requesting adjusting rotation stage angle does not change the power after locking out the controller.

It's currently laser SAFE (the PSL light pipe has been shuttered as normal), but in case we need the PSL light for alignment later, I figured we'd get the procedural stuff done before we need it. Due to IMC particulate concerns, we wish not to have higher than ~100 mW in-chamber while in air, so as to not burn stuff into a flashing IMC (see M1300464).
