This thing really didn't want its modes matched. I had to open up a can O' parameter space on it. Notas:

• I added a static lens in front of the NPRO as well to change the mode I was working with
• I extended the path length (will have to use some folding mirrors)
• I checked that dwaist/dposition was dominated by one of the mirrors by about a factor of ten, so I might actually be able to fiddle with them easily once theyre in place and the PMC is locked.
• I tried to avoid making any nasty waists on the table, the one that does exist is bigger than 100 um radius, and MAY PASS OVER WHERE I HAVE A MIRROR CURRENTLY!

121 um waist with 1.5 Watts is about 3*10^3 W/cm^2 - is this fine to sit pretty much on a mirror,

• Damage thresholds for CVI coatings seem to have several to 10 "J/cm^2" for 20 nanosecond 1064 nm pulses\
  • This means it can take 500 MW/cm^2 for 20 ns - unless I know how often these pulses happen I'm not sure how to make this a CW number
  • To turn this into a normal number I assume I just do "1 J / pulse lase rate / cm^2" - I have no idea what rates are common for pulsed lasers
• CW damage thresholds of materials seem to be order "MW/cm^2" - and if these are what's quoted by a company, it would seem that their coatings would have to not be many orders worse than this (or else the number would be meaningless) - though these companies have done other ridiculous *&!# before so...

I would appreciate any input from the peanut gallery - for now I am inclined to think that 1.5W on an HR mirror with a 240 um spot size is fine.
