Monday 12/15

  1. We went through a checklist of things that still needed to be mounted, and decided to change the layout of laser position a bit to include a dogleg so that the laser connector had more room, free from the cable connectors near the feedthrough panel
  2. Redesigned the feedthrough panels, now the same design can be used for all 4 tables (2 at each site) – and got a quote to be ordered
  3. Connected and tested the laser interlock 
  4. Mounted and installed laser (SN 0918) & cooler, confirmed that it draws current & delivers a reasonable amount of power as read out on the powermeter
  5. Assembled pedestals for the lenses & various optics using assorted spacers to ensure center of all optics is at 4” height
  6. Started a cart for additional components that we’ll need since we’re dipping into table 2 parts due to the adjustments we’re making to the layout

 

To Do:

  1. Finish mounting the mirrors in the flipper mount (supposed to be a double mirror)
  2. Mount the ZnSe QPD 2” lens.
  3. Implement the dogleg
  4. Align the optics
  5. Profile the laser where the translation stage is now or where the beam is supposed to be going.
  6. Integrate the power meter into a laptop with a usb?
