No, but if the beam were of sufficient size it could contain a small amount of mass (theoretically). Also, unless the Laser where shot through a vacuum tube (sterile) then it may contain some elements of dust particles in the beam. Other than that, no, a laser is just "coherent light." Light waves all traveling at the same wavelengths.

Laser beams consist of just light (or electromagnetic radiation), but sent out all in (nearly) the same direction, rather than say a flashlight where the beam gets wider and wider the farther it gets from the flashlight. No matter (i.e., no atoms) in it.

No, it consists of fotons.
Although fotons sometimes behave like particles they have rest mass zero and they form electromagnetic light waves.

The energy does not, but the dust in the air is another matter.

no i don't think so, it contains elements of light
