The following simplified mechanism captures some of the features of a 3-level laser: X+ hv -→ I I → A A → X+ hv’ r= kp f(hv)[X] r = k(IC1) [I] r=kf [A] r = kị f(hv') [A] pumping intersystem crossing spontaneous emission lasing hv' + A → X+ 2hv' f(hv) = flux of photons with energy = hv f(hv') = flux of photons with energy = hv' (usually a constant value) (a constant value different from f(hv)) Note that spontaneous emission (usually fluorescence) is detrimental to efficient lasing. a) Sketch a diagram of the system and identify all the states including metastable states also known as intermediates. b) Derive the steady-state concentrations for all metastable states. c) Show that population inversion ([A]ss/[X] constant is much larger than the sum of the rate constant of spontaneous emission plus the lasing rate constant.
