Abstract
LASER technology is something that we use almost every day in our lives, but don’t even think about it. It has been used to make huge scientific findings and can help us in many ways. A LASER is a coherent and focused beam of photons. LASER stands for Light Amplification by Stimulated Emission of Radiations. This paper describes the LASER technology in details. This paper describes the history and extensibility of LASER. It also explains the concept of principles of LASER technology and how a LASER works? This paper also describes the different types of LASER and the application areas of LASER. Different types of LASER have different operation wavelengths and pump source. This paper also gives the knowledge on how the LASER beam is made and what components are required to make a LASER. The output of a LASER is a coherent electromagnetic field.
