Fiber amplifier

For investigating Ponderomotive effects, we may need ~100 kW circulating in the arm cavities. For this, we are looking at getting an amplifier to boost the 1W input we have right now. Some formal quotes / info from talking to sales reps:

After talking with NeoLase, one candidate is the NeoVan-2S-HP.
- 25k euro.
- 30W out for 1W in.
- Quote and specs: Quote.
- Paper about this amplifier performance: OL.44.000719
- Optional air cooling in case we want to avoid water cooling.
- Need to confirm that the amplifier can be integrated with out Acromag slow control system.
Quote from OpticalEngines: Quote_opticalEngines
- 50k$
- maybe we can have something cheaper if we supply 1W instead of their spec of 30 mW?
Spoke with rep from NPphotonics - expected quote is <$30,000 for an amplifier only.
NuFern (now Coherent) does not make amplifiers anymore, only MOPA.
IPG Photonics YAR-LP-SF
- 30 W output for 5 mW input
- ask them about 500 mW -> 30 W

Power Calculation

P_arm = Plaser * T_PMC * T_IMC * T_FI * alpha_MM * G_PR * T_BS * G_arm

Why Fiber and not Free Space ?

Because fiber seems to be the way of the future...
