dont think it should exist to be an armed-to-the-teeth thorn in Russia’s side
I live right next to Russia, an hour's drive from the border. One thing many westerners don't seem to fully grasp is that Russia is a very blatant bully state. Always has been, for centuries. Russia as a state goes by the motto "might is right" and only understands the language of violence, or threat of violence. This is why all of us in the small states in the eastern parts of Europe are/were so eager to join NATO and arm ourselves to the teeth—it's the only way we could avoid being steamrolled by Russia's imperialist ambitions and incorporated into their corrupt authoritarian hegemony.
I don't like what US and by extension NATO has been doing in the world, either (project Gladius, South America, Cuba and all that shit), but Russian hegemony is much worse. At least we have freedom of press, LGBT+ rights and somewhat functioning democracy under the western hegemony. For small players it has always been the choice between joining one hegemony voluntarily or (attempted to) be incorporated into a worse hegemony violently, as we see with Ukraine now.
You don't need to point it at eyes to blind someone. At these power levels a diffuse reflection from a matte surface is enough to blind. Basically, anyone accidentally seeing the laser's light spot without protective goggles tuned to the specific wavelength of that laser will go blind. Laser weapons are ridiculously dangerous to anyone around, including the user themself.
They only make sense in space warfare where a.) power levels used measure in megawatts so that going blind is the least of your problems, b.) not much surfaces around for the beam to reflect from, c.) windows on warships don't make sense—in fact, crews on spaceships make little sense, too.
