I am writing a SciFi story but I don't like Rayguns

[SleipnirTheHorse]

Well, the reason is because of the opposite, the aliens don't want to kill unless they absolutely have to. They take prisoners according to Galactic Convention.

By the way the aliens are kinda in an accidental war with humanity. Basically we blewup a spaceship out of a misunderstanding and a Galactic WWI situation broke out with most of the Galaxy going to war.

1.) Any laser gun powerful enough to shoot a hole in somebody can probably instantly blind you if it hits your eyes. Even if it just reflected off something shiny. It is a danger to anybody nearby, with "nearby" defined as "closer than the horizon."
2.) It takes lots of tricky engineering to make a laser bolt do more damage than your average bullet. And to be more efficient than your average bullet
3.) Shooting a continual laser beam at somebody is like spitting into the wind. Vaporizing metal or flesh from the target will mess up the beam. Instead the beam should be a series of short pulses.
4.) Lasers need large batteries because they are power hogs
5.) A "heat-ray" is a continuous beam laser. It is like a flame-thrower. Made of energy beams
6.) A "blaser" is a pulsed beam laser. It is like a bullet. Made of energy beams
7.) A laser aimsight can be the actual weapon optics, much like an SLR reflex camera eyepiece. This makes the aimsight vastly more accurate than iron sights
8.) If you are having a raygun fight in an atmosphere, you want the laser gun to use some color of visible light or near-infrared frequencies
9.) Particle-beam weapons are far more efficient at doing damage to the target compared to lasers
10.) Particle-beam weapons can give serious doses of deadly radiation to the gunslinger, due to radiation backscatter
11.) Plasma weapons do not work

Energy Weapon Sidearms

EDIT: This is meant "tongue-in-cheek".

I assume then you have an in-story reason why these (apparently) non-violent aliens didn't, or couldn't, try diplomacy and negotiation to try to de-escalate an impending war. Presumably, they are smart enough to know that (non-blaster weapons or no) galactic war is a very good way of getting of a lot of entities on both sides dead.

Why not a rail gun?

I was about to post that too.

By the way, here are two of the most hilarious weapons in fiction (computer games):

1. BFG9000 (plasma gun in Doom):

The initials composing the weapon's name stand for "Big F***ing Gun."

2. Shrinker (Duke Nukem)

I remember laughing so much using that weapon against fellow players at work (and having it used against me). It shrinks the opponent to a tiny version and then you stomp on them with your foot to squash them.

Edit: here's a video showing it:

the BFG 9000 was great but there were never enough plasma cells to use it much. I do remember hacking the double barrel shotgun to
give it the same rate of fire as the chain gun, which would shred anything

If you have a sufficiently advanced civilization, then a projectile with an antimatter and matter compartment that combines upon impact.

If you have a sufficiently advanced civilization, then a projectile with an antimatter and matter compartment that combines upon impact.

Utter and unilateral annilhilation of everything in a radius of the projectile's impact seems counterintuitive for a society who "don't want to kill unless they absolutely have to".

Not to mention the burst of high-energy gamma radiation ...

I have an advanced race of aliens, but I want them to use a Projectile Weapon.

I've written that they have high-density propelled by a plasma explosion, inside a chamber of a powerful and strong gun.

I highly recommend reading Larry Niven's 'Known Space' stories with particular attention to Ringworld. I think he does a great job of creating plausible alien cultures with different perspectives on what weapon to use when and why. Also does a great job of world building.

I want them to use a Projectile Weapon.

What sort of velocity would these weapons give the projectile? 'Realistically', they would not be near c and the transit time would make guidance difficult with a moving (dodging) target. You'd have a choice of projectile mass; heavy and you'd have recoil problems, light and atmospheric drag would slow them down over distances.

I have been 'put off' personal rayguns as an idea ever since a went to a lecture about practical laser weapons. Whilst they are probably useful as heavy weapons, the energy requirements for a hand weapon make them pretty impractical. So I can see how hand projectile weapons could be attractive.

However, in fantasy fiction, anything goes - so don't come to PF for serious advice; just write convincingly and get your readers to suspend disbelief (as do all good authors). That's the beauty of the Azimov generation; we accept cigarettes and impossibly high transport speeds and the books entertain us. Very little SciFi can survive detailed examination but why should it?.
