WebOptical pumping is a process in which light is used to raise (or "pump") electrons from a lower energy level in an atom or molecule to a higher one. It is commonly used in laser construction to pump the active laser medium so as to achieve population inversion . WebThis type of optical inversion was first observed when an attempt was made to transform malic acid into chlorosuccinic acid in presence of a phosphorus pentachloride. This type of inversion can be used by many optically active substances and also with various reactants.

WebWhat is the relation between stimulated emission and population inversion? Lasers have an optical gain medium in the form of a material (solid, liquid or gas) that amplifies the emitted photon beam. The optical gain medium is analyzed in terms of shape, size, concentration, and purity. Population inversion will occur if the no of particles in ... WebA population inversion (N 2 > N 1) has thus been achieved between level 1 and 2, and optical amplification at the frequency ν 21 can be obtained. Because at least half the population of atoms must be excited from the ground state to obtain a population inversion, the laser medium must be very strongly pumped.
