Laser Amplifier
Vendor Info
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.
- Rana contacted Aug 7 to enquire about 20 W output w/ air-cooling only and 20 mW input.
Quote from Optical Engines:
- 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 <$30,000 for an amplifier only.
- Re-contacted them on 25 June 2019, waiting for a response.
Rana contacted Arturo on June 25 Aug 7; waiting for reply.
NuFern (now Coherent) does not make amplifiers anymore, only MOPA.
IPG Photonics YAR-LP-SF
- 30 W output for 5 mW input
ask them about 500 mW -> 30 W (44 k$)
quote: amplifier.pdf
- IPG Photonics fiber amplifier for a low power seed:
- 20W output with 3 mW input
- Johnny Poon says its $35k
RPMC is just a distributor. The Amplifiers are made by BKtel
$15k for 20 W. 1064 FC amplifiers
- if we use a 20 mW seed, they add a pre-amp (cost increase by ~2.5k$)
- contact - Shawn Smith
BKtel webpage claims 40W output for 30 mW input. Seems exactly what we want.
- Got in contact with them today (25 June 2019), waiting for a response
- Oct 9: No response, crappy webpage
Commentary from Rana (Aug 7, 2019):
The NeoLase stuff is probably the highest quality, but also expensive? Maik should reply by Aug 13.
- Optical Engines, IPG, NPphotonics, all seem more expensive with little benefit.
- My reco is that we go for RPMC/BKtel as long as their responses seem OK to us.
- We'll have to get 3-4 quotes for competitive bidding instead of sole source justification.
Power Calculation
See Power Calculation page 
Why Fiber and not Free Space ?
Because fiber seems to be the way of the future...
What's the price / ease-of-use difference for the free space vs fiber?
If we continue with the 2W NPRO, we would use the free space amplifier, but its possible to use a RIO Planex with a fiber amplifier.
