Abstract: We revisit the basic principle for lasing : Population inversion which isnevertheless closely linked to the negative temperature state innon-equilibrium thermodynamics. With the introduction of quantum degeneracies,we also illustrate their relationship with the lasing via the tuning ofpopulation inversion.
