    You will not be able to guide your sparks down a CW laser beam no matter how powerful. Depending on the duration, air needs around 40 Gw/cm^2 to ionize. Now, the universe is statistical and at much lower energies there is a possibility (however improbable) that a few atoms in the air, argon being the most likely, will ionize, but one or two ions will not guide your laser. If the air contained dust that is highly absorbent to the laser wavelength then a very intense beam might ablate this dust and if it burns in the oxygen then the heat will ionize the gas and you will get favorable conduction. However, this is more likely to result in something like a fuel/air bomb because the heat will also likely lead to an avalanche of additional dust particles burning even where they were not illuminated.

    The military investigated using ultra-fast pulsed lasers to bore an ionized channel through the air so that following pulses would find a focusing effect to counteract divergence.

    Again, pulsed lasers have been investigated for directing lightning discharges in the same way rockets were used decades ago because of their ionized plumes.

    What about a vortex cannon? The pulse of low/high pressure air will probably effect the route a discharge takes through the air. Air's dielectric strength is very sensitive to pressure.
