Explanation Population inversion is the essential process that should take place for the working of lasers. In population inversion the population of photons in the excited state will be higher than the population of ground state which is not usual. Stimulated emission is the process by which these excess photons from the higher state is made return to the ground state by emitting a photon. When an external photon reaches the excited state the energy of that photon is absorbed by the other photons and they emit the excess energy to give a new photon of same phase and intensity...

Atomic Spectra

According to the Bohr model of an atom, the electron in an atom moves around a nucleus in fixed orbits with specific energies known as energy levels. The orbital energies are quantized. The electrons remain in these energy levels until they emit or absor…

Ruby Lasers

Lasers are devices that emit light using atoms or molecules at a certain wavelength and amplify the light to produce a narrow beam of radiation. It works as per the principle of electromagnetic radiation. Their source of emission contains the same freque…

Balmer Series

The spectrum of frequency observed when electromagnetic radiation is emitted from an atom when it goes from higher energy state to lower state, is known as emission spectrum. This transition occurs when an excited electron moves from higher to lower stat…

Emission Spectrum

Every state of matter tries to be at minimum potential energy or it can be said that the atoms of element/ substance arrange themselves such that overall energy is minimum.
