So interesting question just popped in my mind....
What would happen if a laser (be it gas, whatever) was travelling at near light speed? Assuming doppler effects are not noticed, what would happen? The cavity of the laser would shrink, so would that affect the wavelength that it emitted? I would think that, because the cavity would be shorter, it would diverge more? But what else would happen?
Obviously, this lasers is travelling at this speed parallel to its emission axis.
