Thanks for forwarding/reminding, Nikhil.  The nice thing is that you have always measured this in terms of the tilt of the diffuser, and not in the angle the laser light comes out at, so if a tilt angle of O(10) degrees is what's needed, that's easy enough.  The next step is to confirm that the measurements in the lab match to the assumptions made in the software model.

Hello,

As requested, I have attached a copy of the last of my slides that details the evaporation optimization as a reminder.

The best choice in this case was a 7 degree diffuser tilt with a 40 degree diffuser.

The 50 degree diffuser has a higher degree of uniformity, but the light loss becomes very large.
