Laser Systems


LASER stands for light amplification by stimulated discharge of radiation. We all know that light is an electromagnetic wave. Each wave has its own brightness and colour, and shudders at a certain angle, called polarization. This concept also applies to laser light but it is more parallel than any other light source. Every part of the beam has almost exact similar route and so the beam will diverge very little. With a good laser an object at a distance of 1 km can be illuminated through a dot about 60 mm in radius. As it is so parallel, it can be focused to very small diameters where awareness of light vitality becomes so high that you can drill, cut, or turn with the ray. It is also possible to illuminate and observe very minute details with the lasers, thus it is used in surgical claims and CD players as also. It can also be completed very monochromic, thus only one light wavelength is existing. This is not the example with the ordinary light sources. White light encloses all colours in the spectrum, but even a coloured light, such as a red LED contains a frequented interval of red wavelengths
