Consider the ideal laser medium behaves as a four-level system and the population inversion between states 2 an 3. The pump excites the atoms to states 3 and 2 at a rate pumping R3 and R₂, respectively. State 4 decays back to so fast. What is the pump rate in the absence of the saturating beam and no oscillation on the state 3? Assume th the degeneracies in all states are different.
