Peculiarities of linear scaling of cylindrical glass active elements of solid-state lasers

Optimization of the glass cylindrical active element (AE) of a solid-state laser is carried out. Dependences of the optical quality of a laser medium on scale-geometry parameters of the AE with different-intensity optical pumping are obtained. The possibility of considerable increasing of the laser efficiency by using an aperture diaphragm is shown. Baltic State Technical University, 1, 1st.
