Abstract

The wide use of the 1.34-μm solid-state laser in optical fibers and in color-center and phonon-terminal lasers as a pumping source has attracted broad attention. We have been able to achieve 82.8-W laser output with a nearly linearly polarized beam at 1.3414 μm using a 5.8-× 111-mmNd:YAP rod with an overall efficiency of 1.15% and a slope efficiency of 2.02%. The fluctuation of the output power at 62 W is < 1 % during continuous operation for 45 min.
