Hey, did anyone see the Nuvonyx 1200 Watt laser diode on Ebay? Does anyone know anything about Nuvonyx? I think they were bought by coherent.
 





I see nothing on ebay for a Nuvonyx 1200 Watt laser diode. Needless to say there is no such thing anyway, even pulsed.

Ebay item number 261955573428 It looks to be an array of diode laser bars, all stacked on top of each other and collimated with optics.
 
Nuvonyx was bought by Coherent. They built high power lasers for commercial and military with their largest commercial laser being 4,000 Watts CW in a 32 lb. package. Each bar inside is 65 Watts? and they are all stacked on top of each to get roughly 1,000 watts per square inch raw beam and then some optics to shape the beam. I am still researching this thing.
 
I see, you didn't mention an array. Then yes this appears to be legit and it seems to also be styropyro's ebay account. If that's so then you can trust this to be the power he claims it to be. If not then styropyro needs to be informed that someone is pretending to be him.
 
I don't think someone is pretending to be him. I think they are just referencing the video he made on youtube. Which, by the way, is awesome! I've seen it myself multiple times. I so want one of those!
 
I wonder if blue lasers will ever be produced in array bars? 808nm emitters produce about 2W of light each and each bar can have 50 diode emitters for 100 Watts per bar. If the new blues are putting out 6W+ per emitter, would it someday be possible to make 300 Watt per bar blue emitters? The heat output would probably be so high that you couldn't get rid of the heat fast enough. Still a 20 Watt or 50 Watt bar would be awesome!
 
Please use the edit button. Don't double and even triple post, it is frowned upon here.

Given enough time in the future I am sure they will be produced in array bars.

It won't be much use to us if they are though, getting a decent beam out of one of those wouldn't be fun :cryyy:. The reason you see 808nm bars and arrays at such high powers is because they are typically used in systems where the beam quality doesn't matter a whole lot. Such as side pumping a huge chunk of Nd:YAG.
 
"Compact" yea sure lol. Once you factor in cooling, not so compact anymore. Not to mention cost. Good luck finding a yag/ktp to handle those powers, and mirrors while you are at it. Would be best for sure, but theres a reason laserscopes aren't small :) (and are watercooled)

Laserscopes aren't small because A) they are arc lamp pumped so need to handle 6kW of electrical power. B) they have a bunch of extra components that allow them to do medical type stuff. They shrink down quite a bit with a half decent conversion for show use.

Saying that, a 500W (Output?) diode pumped YAG would still be rather beefy, but probably could be made a little smaller than a scope :) If we are using 500W pump power then size would be much smaller again. Lots of variables to consider, pump geometry, cavity design, power supply design, water cooling system design.

Depends on how you define compact I suppose...


Edit: This is a 50W (Output) Q-switched YAG - Pump power is probably ~120W or so:

Nice little 2U power supply!
