The lightning on the laser emitters looks much better than before, the two red bars look very strange though.
You said it's mean to look like those guns from cartoon laser guns, but the way it overlaps with the old emitter looks very weird. I think it should be one or the other, either just the emitter in the old style, or the disk from the cartoon laser gun. Usability-wise, the old emitter is fine, you can just put it in front of the laser beam and it'll cover the excess part of the laser beam.
The other style could be cool too though, not sure it could be made to look good when just floating in air though.
