Laser rifle

Laser rifles are high-tech weapons that emit a concentrated beam of coherent light, with sufficient wattage to do considerable damage. They can be powered by battery packs, fusion cells or cabled power systems, but most models use an internal capacitor, charged with microfusion cells.

Background
Several different models exist, from low power home-made versions to extremely powerful military weapons. As with all energy weapons, laser rifles can suffer from poor performance if not properly maintained. The crystal arrays and non-mechanical components are delicate and if not properly serviced can lead to a loss of beam intensity, overheating, and energy regulation failure. Given that laser weapons were still in their infancy as regular military weapons, parts can be hard to come by in the wasteland. However, their lack of moving parts (aside from the microfusion cell holding latch and trigger mechanism) means they are resilient against extended use.

Apart from rifles, other laser weapons also exist: laser pistols and Gatling lasers.

Wattz 2000 laser rifle


The Wattz 2000 laser rifle (also referred to as the Sunbeam laser rifle ) uses microfusion cells for more powerful lasers, and an extended barrel for additional range. On page 42 of the March issue of Future Weapons Today, there details the story of a Wattz 2000 laser rifle in the hands of a Marine sniper in Nanjing, China.

AER9 laser rifle


 The AER9 was actually not the top laser rifle in service at the time of the Great War. The model line went up to the state-of-the-art AER12, which saw service in a handful of specialty units. The reason that the AER9 is much more commonly found is that it was much sturdier and more reliable than the models that followed. A new model, the AER14, was in development prior to the war, with at least one working prototype surviving in Vault 22.

The AER9 features a titanium housed crystal array which proved to withstand long years of exposure to the elements much better than the gold alloy housing of the later models. As a result, the crystal arrays stayed focused within operating parameters, rather than falling completely out of focus like the newer models. Power is drawn from microfusion cells and processed through a wave/particle diverter manufactured by General Atomics International. The diverters are protected by a carbon-fiber housing, preventing frequent malfunction, but when a diverter fails the weapon becomes unusable.

AER9 Metal Blaster


 The Metal Blaster is a unique laser rifle that fires nine laser beams while expending only one microfusion cell. Everett explains that it was created by a man from The Pitt using parts he found lying around The Mill, including a series of prisms that split the beam. Everett came into possession of the rifle by looting the man's corpse in the Mill.

Tri-beam laser rifle


 The tri-beam laser rifle is essentially a "laser shotgun", which fires three laser beams with each shot. Compared to the regular AER9, it's missing the tube on the bottom length of the barrel, is shorter in overall length and has a new emitter aperture and attached wires. 

AER12 laser rifle
The AER12 laser rifle was considered cutting-edge state-of-the-art technology before the Great War and was used only in a handful of specialty units. However, it is not as reliable as the older models like the AER9 or the Wattz 2000, as the focusing crystal array is housed in gold alloys, more vulnerable to years of exposure to environment.

AER14 prototype laser rifle


 The AER14, a successor to the AER9 and AER12, was a prototype in development before the Great War. The unit found in Vault 22 is one of these development models, complete with exposed wiring and loose prototype circuit boards taped to the stock.

The AER14 is similar in appearance to the AER9, although it is a lighter gray scheme with an orange-red trim. It also has two integrated circuit chips housed inside its stock, which are connected to the rest of the weapon via wires. It uses two microfusion cells per shot. The AER14 also fires a green laser instead of the normal red laser. 

Recharger rifle


A specialized laser rifle designed to work with microfusion breeder ammunition, the recharger rifle effectively has unlimited ammunition. The recharger rifle is also an incredibly sturdy weapon and requires less skill with energy weapons to use effectively. However, this particular rifle is much weaker and heavier than the more common AER9, and the user must time their shots to compensate for the weapon's need to charge up its shots.

Laser musket


A post-war invention used primarily by the Commonwealth Minutemen, utilizing various recycled parts including an AER9 barrel and a wooden rifle frame. The laser musket utilizes a hand-cranked capacitor, requiring the user to crank it after each shot.

Institute laser


A large energy weapon developed by the Institute from the ground up. It is standard issue for Institute scientists, Coursers, and standard Gen 1-3 synth foot soldiers and workers.

Home-made laser rifle


This is a poor excuse for an energy weapon. This garage-rate rifle has terrible accuracy and it doesn't even fire very fast. But any energy weapon is better than no energy weapon at all.

Lightning gun


The Lightning gun fires, essentially, a basic laser rifle's laser. At the point of impact it generates a natural gas cloud. After a moment, a second laser flies in (horizontally, from a seemingly arbitrary location) towards the gas cloud to ignite it.
