Has anybody experimented with the 10W+ IR diodes?

I've seen some c-mount, f-mount, and rarely a TO-9 808nm diodes with claims of 10W power levels. They're single emitter and not the FAP/arrays we've seen on the forum. I'm not sure they're legitimate, but they've got a price tag like they are.
I'm sure they're intended for high power DPSS.

Anybody that's into IR illumination or serious burning messed with them at all? Seems pretty interesting to me for use in a CNC if I could get it to cut balsa well. Would make a scary invisible laser pointer though.

Here are some eBay links for examples, but they're far from the only ones for sale online:

808nm 10W High Power C Mount Laser Diode | eBay

808nm 15W High Power C Mount Laser Diode | eBay

10W 808nm Laser Diode F Mount with Fac Lens | eBay

Edit: I guess they wouldn't be good for burning wood, but I'm sure there are tons of uses. Alaskan and Hemlock Mike both have 808nm bar diode FAP projects, so this would be similar but likely with better beam specs.
