Abstract
A new cavity for diode side-pumped solid-state lasers was designed, built, and tested. The results were efficient absorption of pumped light in the me dia and homogeneous: pumped-beam distribution under various pump-power leve ls, which generated Nd:YAG active media of different radii and concentratio ns and shifts of the diode wavelength. Full-multimode quasi-continuous pump operation with a slope efficiency of 40.5% was obtained from:a plane-plane resonator equipped with two Nd:YAG rods. Ata maximum average pump power of 1.33 kW, the optical-to-optical efficiency was 31.4%. Single- operation (M -2 factor of less than 1.1) of 163 W was demonstrated.
