And that, my dear Khan, is why I prefer particle beams to straight up lasers. Same concept as the guns of mass effect, but firing millions of atomic particles instead of one sand-sized one. Much more energy delivered on-target, with the advantage of being a sustainable attack if one shot doesn't get the job done. They also have only one of the disadvantages you listed for lasers (EMP's), and all of the advantages of them combined with most of the advantages of traditional projectiles. And the EMP thing isn't even a weakness exclusive to directed energy weapons, as chemical propellants can only push a bullet so fast. If you want to exceed that limit, you have to get into the realm of rail guns and then you have the same EMP problem as pure energy weapons.
I consider Particle Accelerator to be in mostly the same camp as any other kinetic impact accelerated weapon.
