Cut Curiously Precise Holes With Femto-Lasers

paymenow points out "this story at Science News Online about femto-lasers and how their novel 'cutting physics' allows much more precision than previous lasers. The technology is now finding applications in various industries including, biotech, automotive and laser eye surgery."

Pulse Speed = Nanoscale Destruction?

[WeaponOfChoice]

Would increasing the pulse speed by 1kx have any effect upon the surrounding material, destructive effects that is. I realise that the pulses are fantastically short but surely going from a thousand fempto pulses a second (roughly 1 trillionth of a second on target) to a million (roughly 1 billionth of a second on target) should negate at least some of the benefits by dint of there being a shorter gap between the pulses to allow the highly ionised material to clear out. This didn't seem to be mentioned in the article so perhaps it's not an issue...
