Laser Amplifier

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 qneuire about 20W output w/ air-cooling only and 20 mW input.
Quote from Optical Engines:
- 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 <$30,000 for an amplifier only.
- Re-contacted them on 25 June 2019, waiting for a response.
- Rana contacted Arturo on June 25 Aug 7; waiting for reply.
NuFern (now Coherent) does not make amplifiers anymore, only MOPA.
IPG Photonics YAR-LP-SF
- 30 W output for 5 mW input
- ask them about 500 mW -> 30 W (44 k$)
- quote: amplifier.pdf
IPG Photonics fiber amplifier for a low power seed:
- 20W output with 3 mW input
- Johnny Poon says its $35k
- YAR-20
RPMC lasers:
- 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.
Amonics
- Got in contact with them today (25 June 2019), waiting for a response

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.

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.
