two laser tubes of different power

[markomadrid]

Is it possible for any Chinese laser engraving machine model (EXLAS, HXlaser, WKlaser ...) to have two laser tubes of different power, in order to exchange them according to the engraving or cutting need (e.g. 60W for engraving stamps, and 150W for cutting 20mm thick acrylic..)?

I'm not sure why you would want to do that, unless you are concerned with the spot size of the larger tube. If so, just swapping the lens would probably yield acceptable results.

If there is something other than the spot size that I am missing, you could get a dual 60W system with integrator and either run one (why?) or both at a reduced power.

Zax ,thanks for your prompt response,it is not matter of spot size of the larger tube.
Chinese laser engraver with 60W are good for engraving but if i must cut thicker material i woul like to have laser tube with 150w.
which Chinese laser have dual 60W system with integrator ?

Why wouldn't you just buy one of the newer 150W system then, you can run it at low power for engraving and turn it up to cut? The only negative is the larger spot size so if this isn't a concern you shouldn't have any problems.

I speak with lots of Chinese laser engraving manufacturer and all of them told me that 150 w is not good for engraving (e.g. stamps....) it is to powerfull.

I think that worst thing in tube swap wil be optical path allignment
