Between the way they worked and their appearance, I'm more inclined to believe it's some "special weapon" of Penny's, or maybe some special Aura Technique of the same "Tree" as Blade Beams (Using Aura to create a projectile).

It might be something that would be too tiresome for a person to use normally, but since she's a Robot she doesn't have such limitation.

Also, since you say "except"....did Penny ever shoot lasers without using that "Giant Laser Cannon" (Which is not giant, nor a cannon)? My point was that lasers and laser-like projectiles in the RWBY universe apparently don't have to have the inherent capability to pierce through things in order to qualify as lasers.

And she fired them while fighting Pyrrha in the tournament. There was a part of the fight where Pyrrha was dodging the lasers, and throughout the episode, there is no damage seen in the floor, despite the trajectory suggesting they would strike the floor. There was also no damage to be seen when Penny used her lasers as a jetpack.
