The establishment of stationary laser generation is preceded by the following transient processes: a) deviation of the inverted population of the working level from the stationary value kinetic nonstationarity; b) nonstationarity due to the finite time of formation of the half-width of the resonator mode -spectrum nonstationarity; c) nonstationarity due to the finite rate of relaxation of the active centers over the states participating in the transition.
