I thought the rainbows that shot out of the end of unicorn horns were "Class V" lasers? Shucks, now I'm all confused.

Class V laser? Are you talking about the laser that's ungodly powerful that the objects that only touch the laser beam once gets obliterated?

Never mind the actual Class V laser in Germany (X-ray free electron laser), that only the professionals are allowed anywhere near the laser control panel. The faculty that houses this huge laser's tightly guarded for this reason as well - laser light of hard X-ray wavelength is extremely bright (about maybe several tens gigawatts) that nothing will survive except for ablative-absorption target.

German engineering is always impressive and of high quality.

Nothing in Physics limits the amount of energy that can be bound into a laser beam. Funnily enough a death star type laser is actually possible :)

If that's true then with more advanced technology, lasers will become WMD's. Then any advanced civilization should eventually be doomed to destruction. Maybe there is a galactic police force out there trying to prevent the proliferation of WMD's. Bionic-Badger has it right, all class 5 lasers must be banned.

True, to the point. It will be impossible to scale, due to thermal limits of lasing mediums as electron confinement is actually important to lasing physics.

Remove the electron bandgap, you have no light at all, and magnets can only take the place of electron shells. The only difference between atoms' electron shells and magnets is that there are a lot more room for wavelength tuning than with specific ingredients in lasing material.

So, simple answer is no. Unless you go with free electron laser - even government-sponsored laser may have to have their huge Neodymium laser crystals replaced frequently due to energy density they have to endure.

Then someone will certainly develop new technology for some new kind of photon emitter that wont have the thermal limits of lasing mediums.

Another reason the building containing X-FEL is full of the security guards who will shoot the trespassers.

Free electron lasers exist for this reason - it's like electron gun in the picture tube, only huge, and use the magnets to wiggle electrons along the poles to force the electrons to emit photons. ***Added*** Electrons are influenced by heat, yes but FEL is in the vacuum atmosphere so there's absolutely nothing to hinder the huge laser from emitting X-ray laser radiation, except for if the wigger magnets gets out of alignments.
