The working mechanism of femtosecond (and picosecond for that matter) micromachining is the same as the coulomb explosion being discussed here. In the industry it is usually referred to 'athermal' or 'cold' to differentiate from the older system which rely on thermally heating the material to ionize it.

In fact it is mentioned explicitly in the wikipedia article:

>Coulomb explosions for industrial machining are made with ultra-short (picosecond or femtoseconds) laser pulses...Coulomb explosion etching can be used in any material to bore holes, remove surface layers, and texture and microstructure surfaces

It sounds like you're familiar with the field, so I'll accept that you're probably correct here, but the wikipedia article doesn't say what you're claiming.

It says coulom explosions are made with ultra short lasers, not that all ultra short laser pulses result in coulomb explosions, so for someone that doesn't know otherwise, you can't infer that whenever someone says ultra short laser cutting that it happens via coulomb explosions.
