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.
