... 4. Consider the 4-level system discussed in class, with the following usual specifications: (i) the pump rate from level 0 to level 3 occurs at a rate P03 . (ii) the decay rate from level 3 to level 2 is instantaneous. (iii) the decay from level 2 to level 1 is by spontaneous emission, at the rate Γ ...
