> while the pulse length is irrelevant

I was thinking along the lines of: 1 attosecond corresponds to .3nm, so very short wavelength, so very deep UV.

The wave length and pulse length aren't the same thing though. The short pulsed lasers actually consists of light that have many different wave lengths in them!

Yes, but shouldn't there be a peak in the spectrum near the frequency corresponding to the pulselength?
