Recent work, three main irons in the fire:
*wide-tune laser design: finally have Zemax working, need to figure out more exact cavity optical path length measurement to inform CAD laser design.
*green beam on-off: installed switches, have the NI-6002 putting out TTL pulses, doesn't seem very stable so far, perhaps pursue a clock-linked design, maybe we could get better stability. Built a TTL or-gate circuit to allow switches to be controlled by delay box or 6002, so far it doesn't work properly.
*EIT parameters: investigating with my simulation to try and decide on good parameters for seeing EIT in the experiment. So far I see evidence of EIT, but there are still a lot of parameters to play with.

Last few days: Little progress, having trouble digesting the new information. We have been making progress but there is still so much we want to do. Did order some parts to hopefully build a laser with a larger mode-hop-free freq sweep and as a very simple NI DAQ to use to turn RF switches on and off.
