Lasers are used more in our everyday life than we could ever imagine. They are used by the police as a way to monitor the speed of a vehicle, used for cutting in minor surgeries, or just used for you remote to your television to change the channel. There are many different kinds of lasers that have a large array of powers starting from the most powerful; an atomic laser to the weakest; an infrared laser. An atomic laser can emit a beam of up to one hundred million volts at twenty-seven million bursts per second. An infrared laser emits about two volts per second. The way these two lasers work are remotely relative, but I am going to explain the basic way most lasers work.

The first part of a laser is the initial start of the light, which is created by an electric spark, jumping from what is called a node to an anode or the negative to positive terminals. When this happens a small amount of light is created i

n a quarts tube filled with typically argon gas. The argon gas is what gives a laser its red color in a laser pointer. This tiny sparks makes light, which is in the form of ions. Ions make up all light in the universe. These ions scatter out at the speed of light in every direction. Most of the ions just disappear the only one that doesn¡¯t disappear is the one ion that travels completely horizontal to the two sides of the quarts tube.

The last stage a laser goes though is the stage were the Light Amplification by Stimulated Emissions of Radiation beam reaches the concaved mirrors, which are affixed at both sides of the quarts tube filled with argon gas. When the beam hits the mirror it bounces back across the tube toward a second mirror, a two-way concave mirror. This mirror will reflect the beam until it has reach the strength powerful enough to exit the tube when this happens the beam of concentrated radioactive ions travels out as a light beam called a laser beam.
