Q. What are the conditions to achieve the laser action?

Conditions to achieve laser action

(i) There should be an inverted population that is more atoms in the excited state than in the ground state.

 (ii) The excited state should be a metastable state.

(iii) The emitted photons should stimulate further emission. This is achieved by the utilize of the reflecting mirrors at the ends of the system.
