Abstract

The report results indicate that the minimum time needed for cw gasdynarnic laser active cavity to adjust itself to a new steady-state defined by sudden change of the boundary gain value and/or of the resonator quality is: (i) in zero order approximation equal to the average time of the excited states residence within the cavity region, (ii) in first order approximation exceedes the mentioned value by several orders depending, moreover, of the sign and type of the perturbation. Within the frame of the summing-up comments a single strongly non-linear partial equation of the third order is formulated. It covers all cases of the non-stationary operation of transverse flow lasres. The problem is treated in the frame of Riigrod-Marlow rate equations description of the active lasers cavities.
