Laser Systems

Laser stands for light intensification by stimulated emission of radiation. We all know that light is an electromagnetic wave. Each wave has its own glare and color, and vibrates at a convinced angle, called polarization. This concept also applies to laser light but it is more similar than any other light source. Every part of the beam consumes almost exact same direction and so the beam will deviate very little. With a good laser an object at a distance of 1 km can be irradiated with a dot about 60 mm in radius. As it is so similar, it can be focused to very small diameters where absorption of light energy becomes so high that you can drill, cut, or turn with the ray. It is also conceivable to illuminate and inspect very tiny details with the lasers, thus it is utilized in surgical applications and CD players as also. It can also be made very monochromic, thus only one light wavelength is present. This is not the instance with the normal light sources. White light consumes all colors in the spectrum, but even a colored light, such as a red LED has a repeated interval of red wavelengths.
