For pulsed IR laser rust removal systems i've seen various power ratings, such as 2kW.
Is this 2kW the peak pulsed power? or 2kW continuous power with a peak pulse power in the hundreds or thousands of kW?

... a German company is selling 1,5kW-fiberlasers for rust removing for below 20k€ ... and its usable for cutting and welding too
Here I was testing with a 20W (NOT kW) and some greasy and rusty parts

Interesting, I was sure they were all pulsed lasers. Looks like i'm wrong.
... with pulsed or CW lasers its either the peak pulse power or the avarage or CW-power, what's enables different applications ... with the 20W fiberlaser with peak pulse power of around 10kW its hard to weld, as its only 20W averaged -- but I could comfortably melt preapplicated solder-paste on a PCB with the not focussed beam ... simply removed the f-theta-lens from the scan-head ...
Here the video from "laser-soldering" - first step "drying" the solder-paste with lower power -- then melting it with higer power - https://www.youtube.com/watch?v=1OW8awSC9z4
With a pulsed laser with 1.5kW it's even much more "powerfull" -- so it's enough heat to "melt" (weld) or even "cut" (evaporete or melt and remove with pressurized air) some mm thick iron-plates ... by the way -- i'm doing this sort of things with IR-laser-diodes with 200W on a spot of 0,2mm too ... but schould be enough "peak power" to clean surfaces too, when fed through a galvo or polygon mirror
