=== Main Laser Upgrade: ===
 1. Keep existing NPRO (save time in laser commissioning)
 1. Use Neolase amplifier from LLO
 1. That requires the amp + diode box + fibers + chiller + controller
 1. There will be some issues with setting up the Beckhoff to run this in this standalone configuration.
 1. Need to figure out where the chiller and diode box will sit.
 1. Need to figure out how to do the CDS interface





=== Old (early 2020) upgrade idea ===
We want to replace the 2W Innolight NPRO with a fast, low noise laser solution.
 * Rio Planex as master Osc
 * fiber EOM for fast phase/frequency modulation (incl the PMC sidebands)
 * 1064 nm fiber amplifier
 * some output optics to go into the free-space PMC that we already have

For investigating Poonderomotive effects, we may need ~100 kW circulating in the arm cavities. For this, we --are-- were looking at getting an amplifier to boost the 1 W input we have right now. Now we have decided to go with the following setup:
 1. RIO Planex (1064 nm) as master oscillator; output ~ 20 mW, see [[RIO_Laser|datasheets]].
    * Commercial (Thorlabs) temperature controller
    * Thorlabs butterfly package
    * How to package for low acoustic sensitivity?
    * Use the latest version of Johannes/Luis/Rich diode driver for driving the current and locking to the IMC. Make sure to order 2 units from Luis.
    * Need fiber to free space thing with low AR / good polish
    * Fiber based PM for locking to IMC w/ high bandwidth.
    * Fiber based AM for intensity servo
 1. 1-2 stage CW fiber amp to take us to > 20 W
