4A2 - The utilization of semiclassical and rate equations for design of steady-state lasers

Semiclassical equations are used to determine the output power of steady-state optical maser as a function of various parameters (pumping level, crystal losses, cavity length, and mirror transparancy). The results obtained are compared with those given by the rate equations theory (as applied to a ruby crystal). It is shown that the difference between these two methods from the technical point of view is insignificant and did not appear in ordinary experiments.
