Wow, good posts everyone so far. 
My response is further down.

optical focusing techniques will not work, how do you know where to focus
the laser beam to zap the invisible guy?

Simple enough; do without the rangefinder. If the laser can adjust it's
range on the fly by moving mirrors & such, have the focus move quickly from
just in front of your weapon to it's theoretical max-range and back again,
therefore slicing neatly through everything between here and there.
Invisible or not, you'll still hurt it if it can be hit.

What is the effect of that kind of energy density on liquids? That is,
could we produce protection by placing a layer of flowing liquid
between target and gunner, so that new liquid flows steadily into the
intersection area even as the pulses vaporize what's there?
