Vedclass · Answer

(D) $LASER$ action relies on the following fundamental processes:$(i)$ Population inversion: Achieving a state where more atoms are in an excited state than in the ground state.(ii) Stimulated emission: An incident photon triggers an excited atom to emit a second photon identical in phase,frequency,and direction.(iii) Amplification: The process of increasing the intensity of light by repeating stimulated emission within an optical cavity.Therefore,all the given options are correct.

The principle of $LASER$ action involves:
