Introduction[edit | edit source]
LASER means Light Amplification from Stimulated Emission of Radiation.Laser is created by specific process within the laser device to cause the controlled emission of radiation in form of light.[edit | edit source]
Production of Laser[edit | edit source]
Laser device is made up of an optical cavity or chamber that contains active medium for which laser is named.The chamber has mirrors on either end that are perfectly parallel to each other within a single wavelength of light.One of the mirror is partially open.Electricity or energy is added to the medium which excites it.The active mediums atoms are reflected back and forth across the mirrors within the chambers.this causes more excitation of atoms within the medium.Laser light is then emitted through the partially reflective end of mirror.The light production occurs in the following steps:[edit | edit source]
1.Electron is pumped to a higher energy level.
2.Pumping level is unstable so the electron quickly jumps to a slightly lower energy level.
3.Electron relaxes to a lower energy state and releases a photon.
4.Light and an electron in an excited energy level produces two photons of same wavelength and phase.
5.Mirror reflects the photons.
