Abstract

We report on a significant improvement in cw laser performance of the disordered Yb:CNGG crystal. Very efficient cw laser operation is demonstrated at room temperature with a 3.5 mm thick crystal end pumped by a diode laser, generating an output power of 5.15 W with an optical-to-optical efficiency of 46%, whereas the slope efficiency amounts to 80%.
