Laser Rifle (Fallout: New Vegas)

The laser rifle is a weapon in Fallout: New Vegas.

Background
The AER9 was not considered cutting-edge technology before the war, being an older model than the state-of-the-art AER12 laser rifle, used in a handful of specialty units. The redeeming feature of the AER9 was its reliability - the focusing crystal array was housed in a titanium casing, rather than the gold alloys used in later models, which allowed it to withstand years of exposure to the environment without loss in array focus.

Characteristics
This variant of the AER9 laser rifle can be upgraded beyond the factory standard. You can attach a sort of computer targeting scope to it. Close to the breach (just behind the muzzle) there appears to be a bright light and the body of the rifle has been painted red.

A "beam splitter" module can also be attached, which causes the rifle to fire two beams instead of one. If both strike the same target, they deal more damage compared to a single beam ("+30% Damage"), but are weaker individually.

A unique AER14 prototype with a green beam can also be found in the game.

The markings on theses rifles as well as their descriptions in game hint at the types of lasing mediums used in each variant. The 1064nm wavelength (frequency converted to green, 532nm) of the AER14 prototype strongly indicates that it is a Nd:YAG (neodymium-doped yttrium aluminium garnet) laser while the ~650nm wavelength of the AER9 laser rifle indicates that it is likely a Ruby, InGaAs or HeNe laser.
