Can it be true? 70W laser diode?

Small CO2 lasers can be air cooled but most are water cooled like the big diode bricks. Efficiency isn't bad for CO2 lasers, they're some of the most efficient of gas lasers.
 





And these diode stacks are flashlight style when it comes to beam profile, even a single diode bar has usually 19 emitters with 500um spacing, making a 10mm line that you need to work with. These areonyl usefull for pumping lasers or anything not requiring a good beamprofile.
 
A lot of this information is easily available ;)

A pump laser is used to excite another medium which in turn lases on another wavelength

intereting!
so back to the initial diode of this threat.
would it be possible to make a heatsink efficient enough to cool this thing while running in non pulsed mode? or would the plastic of the diode melt before the heat can reach the heatsink?
 
I doubt it would be able to run CW at all, it would have a threshold too high for operation before it would melt itself
 
so I guess if you dont want it to get too big but still want quite some power pumping diodes would be a good idea?
