Abstract

Nearly quantum-defect-limited laser operation of a resonantly pumped Er 3 + : YVO 4 at 1593.5 nm is demonstrated. Maximum slope efficiency of 85 % and true CW power of 13 W at 1593.5 nm were achieved with a beam propagation factor of M 2 1.05 . This slope efficiency is, to the best of our knowledge, the highest efficiency ever reported for a crystalline Er-doped laser.
