laser amplitude question

[infraray]

A phrase was used the other day that gave me rise to question, and that is frictional amplitude. Has anyone ever heard this phrase in the context of lasers especially cutting. Not knowing enough about lasers just yet I can neither confirm nor deny the validity of the phrase. I have done searches on the web but only came up with a few geography references. I smell something fishy and am hoping to get some evidence. Any help would be appreciated. :confused:

Just a guess, but from the context of your post "frictional amplitude" may be referring to an adjustment required of output laser power with respect to the material(or section thereof) being cut.
