 A laser would heat up the enclosed gas, wouldn't it? If enough sustained heat increase occurred, couldn't that induce the balloon to burst?

 All,
The nice thing about an electrically powered laser -- if you miss -- just squeeze the trigger again [essentially each round is free] -- with the exception of burning some jet fuel you can keep shooting

All,
Its more complicated -- in a vacuum yes the spreading is easily predictable
However in a gas with enough power the laser beam can essentially make a "virtual fiber optic" by the heating of the air in the core changing the index of refraction of the beamIf the power density is really high the air will "breakdown" and the core of the path will be ionized gas changing everything you heard about in grade school physics
