The AER14 laser rifle was in development stages before the Great War, designed as an upgrade of the AER9 and AER12 models. Using the original AER9 chassis as basis, the weapon has modified optics and focusing crystals, resulting in a more focused and destructive laser beam. As a side effect, the frequency of the amplified light is shifted, resulting in a green, rather than red laser beam.
A single AER14 prototype is confirmed as existing by 2281. This development hardware platform was lost in Vault 22 and still retains its workshop markings and jury rigged circuit boards rigged to the stock. As the development cycle was not finished, the AER14 has power consumption issues, using up twice as much power per shot, and is more fragile compared to its predecessors.
The AER14 has a lighter gray housing than the standard laser rifle along with a black foregrip. The front bit of the barrel as well as the rim of the stock is a distinct orange color. Green and yellow wires attach from the main action to the front of the rifle and red and blue wires attach from two computer chips in the stock to the main action.
The AER14 uses two microfusion cells per shot and has a unique green laser instead of the normal red laser, different from a standard laser rifle. It doesn't have iron sights view and cannot be modded using laser rifle mods, though it can be repaired with normal laser rifles.
Vault 22, it is located in common area. Go to the fifth floor, Pest Control, and enter the stairway door to the common area which has a lock with a difficulty that varies according to the players level. The AER14 is laying on the ground next to a scorched skeleton. Beside the AER14 prototype are several energy cells, even though the gun doesn't use that type of ammunition.
Prior to patch 126.96.36.1994, the AER14 dealt only 22 points of damage per shot.
Behind the scenes
There is a sticky note on the observable back of the weapon that says "Focus: 1064 nm, 532 nm (SHG), 8.18pm !!!" This refers to the wavelength of the laser light, 1064 nm (infrared) being the fundamental wavelength of the laser and 532 nm (green) being the second harmonic. SHG stands for Second Harmonic Generation, a frequency conversion process that uses a set of crystals that double the frequency of the light making an IR (1064 nm) light look green (532 nm, half 1064 nm). 8.18pm is slightly more ambiguous, this likely stands for picometers, and if so is likely the beam divergence which is often measured pm/m (picometers per meter, and more often used mRad) and is the rate at which the beam dissipates, expanding into a cone.
I designed it. The science and math involved were the result of me doing some basic research and consulting with a friend who is experienced in laser physics.
As for why I did it in the first place, to paraphrase Charles Eames, details aren’t details. Details are the design.
