Continuous-Wave 2 W Green Light Generation in Periodically Poled Mg-Doped Stoichiometric Lithium Tantalate

摘要

A stable continuous-wave output power of 2.06 W is demonstrated at 542 nm by single-pass second-harmonic generation (SHG) with periodically poled Mg-doped Stoichiometric lithium tantalate (PPMgSLT). The laser linewidth effect on SHG efficiency was investigated with a Yb-doped fiber laser.
