There are several laser applications in the scientific, medical, commercial as well as military field since it was innovated in the year of 1958. It has several properties which make it greatly applicable in several industries. Some of the properties include high monochromaticity, coherency as well as the ability to attain extreme high powers.
The common use of laser sight is among the military personnel for designation and ranging of targets, defensive countermeasures, communications as well as directed energy weapons. It has also been declared by the Northrop Grumman that its engineer is Redondo Beach who had successfully built and also tested an electric laser which can produce a 100-kilowatt ray of light, powerful enough to nullify cruise missiles, rockets, artillery as well as mortar rounds. An electric laser is in theory able to be mounted in an aircraft, ship, or vehicle due to the fact that it has a much smaller space requirement for its associated equipment when compared to a chemical laser according to Brian Strickland, the manager which is in charge of the United States Army’s Joint High Power Solid State Laser program.
Several firearms applications make use of the power of the laser so as to enhance the targeting of other weapon systems. For instance, a laser sight is a tiny but visible light laser which is erected on a handgun or a rifle and aligned to send out a beam which also runs parallel to the barrel. Usually, the laser sight is a visible laser light which enables the shooter to see the point where the bullet is directed. It is usually found above the body of the small arm at the angle facing down, so that the laser will point directly at the spot where the bullet will enter. However, the laser is not so accurate and there may be a small shift but this does not matter because it can easily generate an accurate hit.
The laser beam has a low divergence which implies that the laser light would appear as a small spot even when the distance is long. The user will place the spot on the chosen target and the barrel of the gun is aligned to shoot that target. However, the laser cannot account for the bullet drop, windage as well as target movement while the bullet travels.
Majority of the laser sight come along with a red laser diode. However, there are some that also make use of an infrared diode to create a dot which is visible to the human naked eye but discernible with a night vision devices. The firearms adaptive target acquisition module LLM01 laser light module has visible as well as infrared laser diodes. Later on, in the year 1990s, a green diode pumped solid state laser (DPSS) laser sight (%32nm) were put on the market. More of the current lasers are tiny and light enough for attachment to the firearms.
Later in the year 2007, LaserMax, a company which deals with the manufacturing of laser for police and military firearms, established the first mass-production green laser available for use in smaller arms. This laser is then mounted on the underside of a handgun or long arm on the accessory rail. The green laser is known to be more visible than the red laser when viewed under bright lighting conditions due to the fact that the same wattage green light appears brighter than the red light.
