Dynamical characteristics of high-power solid-state multirod laser resonators
Using the concept of equivalent resonators, dynamical characteristics of highpower solidstate multirod laser resonators are analyzed. The general expressions for equivalent gparameters and equivalent resonator length of multirod resonators are derived which permit us to obtain the dynamical characteristic curve and critical refractive powers on the equivalent gparameter diagram for multirod resonators and to illustrate their dynamical characteristics with numerical examples. In addition, the method of compensating a discrepance of the refractive power by a suitable adjustment of the distances between the mirror and the rod is discussed and the related analytical formula is given.
