Maybe with Q-switched lasers or something, but not a CW diode. You put 20 W DC in and get 10 W of light? Can you point me to a data sheet for such a device?
(Maybe I've been away from this sort of gear for too long, and there are real developments, but I have my doubts.) And, I've seen all sorts of impossible claims in Chinese laser blurbs, but they are clearly lies. Stuff like 5 V at 100 mA gives 1 W output!
