Abstract

We have demonstrated 7.6 W of continuous-wave radiation at λ = 1.06 μm in a TEM₀₀ mode from a diode end-pumped Nd:YAG laser pumped by 38 laser diodes that are coupled to a bundle of 19 fibers. TEM₀₀-mode operation was enforced by using an intracavity aperture. The absorbed power in the Nd:YAG rod was 16.4 W when the incident power upon the laser rod was 21.1 W. The optical-to-optical conversion efficiency was 46%. In multimode operation, 11 W of output power and a slope efficiency of 69% were obtained. The thermal analysis was in good agreement with interferometric measurements.
