Today Dick assembled the DC PDs we needed and Filiberto and Aaron added some cables so that we could get the PDs going tonight.  

I leveled the beam and aligned it along the bolt holes, and added the PLCX-50.8-309.1 16 inches from the bottom periscope mirror, and the f=143 lens 10+1/4" after that.  This resulted in a waist of 16 um, by moving the 2 inch lens back 6 cm I got a 18um waist, the measurements are attached.  In these plots 0 is 394 mm from the inner edge of the enclosure walls.  

I then installed the crystal, which was labeled 1x1x10mm PPKTP but was not square but rectangular.  It was in the box mounted in a holder that must have been part of the comerical SHG oven.  I tried to align the beam through the crystal, but it was difficult to see what I was doing so the crystal position might need adjusting.  We will need another lens right after the oven because the beam diverges quickly after the 18um waist.  

I did not optimize the temperature, but measured 67 uW of green produced.
