* Realized the whole mounting scheme won't work because the Thorlabs rotation/translation mount is too large. Will rework design tomorrow to use [http://search.newport.com/?x2=sku&q2=9081 this mount] instead. Will likely have to buy more aluminum and copper stock (gdosafjoijforngoasjf). May look into getting the copper part of the mount outsourced - it's going to involve fairly precise machining on a small piece, and the shop will be closed for a week and a half anyway. The aluminum part I'll do next week. |

- Realized the whole mounting scheme won't work because the Thorlabs rotation/translation mount is too large. Will rework design tomorrow to use this mount instead.

- Cut channel into diode laser mount. Waiting to drill screw holes until I get the part to see if I need to mill any more out to make it fit.
6/16/2015
- Got questions back from Thomas at Layertec. Sent answers. They're working on a quote.
6/15/2015
- Ordered water blocks from Custom Thermoelectric.
- Ordered rotation/translation mount from Thorlabs.
- Designed channel cut for diode laser water cooling modification. Looks like it should work with no problems...
- Designed crystal mount.
- Ordered crystal mount copper/aluminum stock.

- Talked to Deniz about lasing direction. Decided we don't need an intracavity isolator for the Ti:sapph laser. The output coupler will provide enough asymmetry to force lasing in the correct direction.
- Sent email to Layertec requesting quote for Ti:sapph cavity mirrors.
- Talked to Zach about design for Ti:sapph crystal mount. Decided on basic design using water block, possibly from here. Crystal should probably be wrapped in thin indium foil for better contact with copper. Also talked about cutting a "channel" out of the diode laser aluminum block to add a similar water block below the TEC.
