The laser has in most firearms applications been used as a tool to enhance the targeting of other weapon systems. For example, a '''laser sight''' is a small, usually visible-light laser placed on a handgun or a rifle and aligned to emit a beam parallel to the barrel. Since a laser beam has low divergence, the laser light appears as a small spot even at long distances; the user places the spot on the desired target and the barrel of the gun is aligned (but not necessarily allowing for [[bullet drop]], [[windage]], distance between the direction of the beam and the axis of the barrel, and the target mobility while the bullet travels).

Most laser sights use a red laser diode. Others use an [[infrared]] diode to produce a dot invisible to the naked human eye but detectable with night vision devices. The firearms adaptive target acquisition module [[LLM01|LLM01 laser light module]] combines visible and infrared laser diodes. In the late 1990s, green [[diode pumped solid state laser]] (DPSS) laser sights (532&nbsp;nm) became available.
