    Default Laser rust removal power ratings, are they peak pulse power or continuous?

    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?

    The rust laser remover is a continuous 2kW focalised 1.064 nm fiber laser . You can use a 500W CW fiber laser only the speed of rust removal is lower !

    ... 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
