I picked up a few of these little guys if anyone is interested. They can be pushed upwards of 80 watts. They're $175/ea +shipping. Not for beginners!

I accept PayPal, Venmo, Cashapp and Crypto. Please let me know if you have any questions.

The datasheet you provided is for a 60 W array, not 80 W.

I have almost pulled the trigger to buy one of those a couple of times now, just wish they made them for a longer wavelength. In the last few months I saw a post and photos a member here put up for one, quite an interesting device. Outputs were more parallel than I expected. I wonder if Redcowboy has been working with one yet.... Right up his alley.

Sorry if this is off topic but how cool would it be if you could build a LEP flashlight powered by one of these bad boys? I have two Acebeam’s and I think the lasers in them are 7 watts or less

Likevii was doing something like this: pumping phosphor with 300W from 3x NUBM31 combined.

Wow… although I know they have white lasers coming too. Not sure how exactly they work - still on the development / lab stage
They don't have white laser coming--is a physical impossibility against the laws of physics.
There is no wavelength of laser light that is called "white", so...

Think again those chips just produce Red,Green and Blue which give/create the illusion of "white" when mixed but if you run it through a prism, out the other side comes RGB which is what it really is.
See: https://phys.org/news/2015-07-world-white-lasers.html
Natural "white" light is a combination of many millions of wavelengths of light. By definition, a laser emits light at only a single wavelength, and so a laser cannot create pure white light.

PS
Wavelength is not color and color is not wavelength. Wavelengths have no "color".
Light is frequency/wavelength. Color is a function of the human visual system, and is not an intrinsic property. Objects don't "have" color, they reflect light that "appears" to be a color. Spectral power distributions of wavelengths exist in the physical world, but color exists only in the mind of the beholder. There is no physical significance in color names. .
A given wavelength of visible light has the same frequency regardless of any observer or lack of an observer viewing it.
Wavelength is a physical property in the physical world---"color" is not, it is the brains interpretation of wavelengths sensed by the human visual system.

Go on ebay and search RGB white laser---there are several ---you can buy a low cost low power version for $50-$75 --buy one and see for yourself what is what. is very interesting.

I know the ones you are referring to - just a red, white, and green beam overlapping to appear white.

but white lasers are different. It a coherent beam of photons of different wavelengths, evenly distributed between a minimum and maximum value.

Not for sale on eBay :)

atom lasers might interest you too. Coherent matter waves using Bose Einstein Condensate: https://en.m.wikipedia.org/wiki/Atom_laser
