What is the Full Form of LASER ?
LASER - Light Amplification by Stimulated Emission of Radiation
Light Amplification by Stimulated Emission of Radiation is an electronic device that produces light (electromagnetic radiation) through a process of optical amplification. These radiation have very special properties that makes them used in a wide variety of applications.
It is used to manufacture a wide range of electronic devices including CD ROMs, Bar code readers, etc. The light emitted by these devices is thin and coherent.
Applications of LASER
