Resumo
Dynamically stable resonators have a stationary TEM00 beam waist inside the laser rod (w30), which is minimal
throughout the stability interval and insensitive to changes in pump power. For a given set of resonator parameters
(mirror radii and distances between mirrors and rods), the stability interval parameters, which are the limits of the
stability interval in terms of the rod’s thermally induced focusing length are determined. In linear resonators, these
stability interval parameters cannot be changed independently only by varying resonator distances, and mirrors of
different curvature have to be employed. However, our group showed recently that for a symmetric ring resonator
containing a pair of curved mirrors, the width of stability interval and the stability interval limit at maximum rod’s focal
length can be adjusted continuously and independently only by varying resonator distances once the mirror radius of
curvature has been fixed. In this work we demonstrate a project of an adaptive ring resonator that allows the TEM00 -
mode resonator to be continuously tuned throughout the whole range of pump powers utilizing standard
electromechanics to move the mirrors. Additionally for a given value of pump power, w30 can be varied, thus allowing
different beam qualities to be obtained from the same resonator.
