* Measured diode current vs power curve. Max is 2.8 W of output power at 3 A input current.
* Drilled a hole in the top of the crystal mount to add a set screw. Slathered the inside of the hole with thermal paste, slipped the crystal in, and tightened the set screw. Crystal is held quite solidly! May still have to redesign at some point, but this will definitely work for now. Some concern over thermal paste on sides of crystal, may want to clean it off at some point.
* Took a first run at the absorption measurement. 2.8 W in, 1 W made it through the crystal, which is 64% absorption if true - doubtful. We're only measuring transmission, so we can't be sure that the full 2.8 W is incident on the crystal. Probable pre-crystal loss mechanisms: scattering, polarization/Brewster losses (although we seem to have landed very close on our rough alignment).
