Question 06 Derive the inversion population condition of the following system. Then, express the condition on the rate R. Kj is the decay rate from the energy level I to the level j. E3 N3 Y32 E2 N2 R 731 721 Laser transition E1 Ni In the Cr3+: Ruby laser, the lifetime of the meta-stable state is 3ms. If the population density is Ni=2.5*1025m?, then find the pumping flux necessary to create the population inversion. Hint: 731 << 732 and y21 is radiative. Is this condition enough to operate a laser?
